1. Valence electrons from the metal and nonmetal collide. 2. An electron is exchanged, with the metal atom losing an electron to form a cation and the nonmetal gaining an electron to form an anion. 3. This results in the formation of two ions - a positively charged cation and a negatively charged anion. 4. The ions are then held together by electrostatic attraction between the positive and negative charges.

This document discusses ionic bonding between atoms. It explains that ionic bonds form when a metal atom donates one or more electrons to a nonmetal atom, giving the metal a positive charge and the nonmetal a negative charge. The document outlines how main group elements gain or lose electrons to achieve a full outer shell of 8 electrons, and provides the example of sodium donating an electron to chlorine to form ionic bonded sodium and chloride ions.
Ionic bonding & covalent bonding
The document discusses two types of bonding: covalent and ionic. Covalent bonding involves the sharing of electron pairs between non-metal atoms to form molecules. Ionic bonding occurs between a metal and non-metal where the metal transfers electrons to the non-metal to form oppositely charged ions in a giant lattice structure. This ionic lattice structure results in high melting and boiling points due to the strong electrostatic forces between the ions.

This document summarizes key concepts about valence electrons, electron dot diagrams, ionic bonding, and covalent bonding. Valence electrons are found in the outermost energy level and interact during bonding. Electron dot diagrams represent valence electrons with dots. Ionic bonding occurs through the transfer of valence electrons between metals and nonmetals, resulting in ions with charges. Covalent bonding involves the sharing of valence electrons between nonmetals. Properties of ionic bonds include conductivity, higher melting/boiling points, and crystal formation, while covalent substances are often gases/liquids and nonconductive.

4-2 Ionic & Covalent Bonding
The document summarizes the key differences between ionic and covalent bonding. Ionic bonds form when a metal transfers electrons to a nonmetal, creating oppositely charged ions. Covalent bonds form when nonmetals share electrons to obtain a full outer shell. Ionic compounds have high melting points, are brittle solids, and dissolve well in water, while covalent compounds have lower melting points, are soft and pliable, and are generally insoluble in water.
Ionic compound
The compounds which are made up of ions are known as ionic compounds.
In an ionic compound, the positively charged ions and negatively charged ions are held together by the strong electrostatic forces of attraction.
The forces which hold the ions together in an ionic compound are known as ionic bonds and electrovalent bonds.
Chemical bonds
Chemical bonding involves the attraction between atoms that forms as a result of interactions between valence electrons. There are three main types of bonds: ionic bonds result from the transfer of electrons between metals and nonmetals, covalent bonds involve sharing of electrons between nonmetals, and metallic bonds are attractions between positive metal ions and delocalized electrons in metals. The number of valence electrons determines an element's chemical properties and how it bonds. Chemical reactions occur through the breaking and forming of new bonds, and equations are used to represent these processes in a balanced way that obeys the law of conservation of mass.
Ionic bonding
Ionic bonds form when a metal transfers an electron to a nonmetal, giving each atom an octet of electrons. For example, sodium loses an electron to form Na+ while chlorine gains that electron to form Cl-. The resulting ions are held together by electrostatic attraction to form an ionic compound, sodium chloride (NaCl). NaCl crystallizes into a repeating pattern where Na+ and Cl- ions alternate in a crystal lattice. Ionic compounds conduct electricity when molten or dissolved due to the movement of ions.

There are four types of solids depending on the bonding between particles: molecular, macromolecular, metallic, and ionic. Covalent bonding forms molecular solids like iodine where atoms share electrons. Metallic bonding via delocalized electrons gives metals properties like malleability and high conductivity. Ionic bonding through electrostatic attraction between cations and anions produces solids like salt that are hard but brittle. The type of bonding determines a solid's properties.
Bonding
There are four types of solids depending on the bonding between particles: molecular, macromolecular, metallic, and ionic. Covalent bonding forms molecular solids like iodine and macromolecular solids like diamond. Metallic bonding results from delocalized electrons binding metal ions into a lattice, allowing metals to conduct electricity and heat well. Ionic bonding occurs between oppositely charged ions, forming ionic solids that are hard but brittle.
IS2 Ionic Bonding
Ionic bonding occurs when atoms gain or lose valence electrons to achieve stable noble gas configurations, becoming ions. Cations are positively charged ions formed when atoms lose electrons, while anions are negatively charged ions formed when atoms gain electrons. Ionic compounds are formed from electrostatic attractions between cations and anions, resulting in electrically neutral compounds. Ionic compounds usually have high melting points and conduct electricity when molten or dissolved in water.

Ionic compounds are formed when oppositely charged ions attract each other. Metals form ionic bonds with nonmetals and crystal lattices. In ionic compounds, the cation is written first followed by the anion to give an electrically neutral compound. Polyatomic ions and oxyanions contain multiple atoms bonded together with oxygen. Metallic bonds are delocalized electrons that are shared between positive metal ions in a crystal lattice.
Chapter 5 Chemical Bonds
1) Chemical bonds can be either ionic or covalent. Ionic bonds form when electrons are transferred between metals and non-metals to form ions. Covalent bonds form when electrons are shared between non-metals.
2) Sodium chloride forms when sodium donates an electron to chlorine to form ions that are attracted in an ionic bond. Hydrogen molecule forms when hydrogen atoms share an electron pair in a single covalent bond.
3) Ionic compounds have high melting points, conduct electricity when molten or dissolved, and dissolve in water but not organic solvents. Covalent compounds have lower melting points, do not conduct electricity, and dissolve in organic solvents but not water.
Chemical Bonding - Dr. Mahbub.pptx
This document provides an overview of chemical bonding. It defines a chemical bond as a force of attraction between atoms or ions that holds atoms together in molecules or compounds. Atoms form bonds to achieve stable electron configurations. There are three main types of bonds: ionic, covalent, and metallic. Ionic bonds form through the transfer of electrons between metals and nonmetals. Covalent bonds form through the sharing of electrons, usually between nonmetals. Metallic bonds involve the pooling of electrons between metal atoms. The document further explores bond formation and properties.
4-4 Ionic & Covalent Bonding
Ionic bonds form when electrons are transferred between metals and nonmetals, resulting in oppositely charged ions. Covalent bonds form when nonmetals share electrons in order to achieve a stable electron configuration. Ionic compounds have high melting points and conduct electricity well when melted but not solid, while covalent compounds have low melting points and generally do not conduct electricity or dissolve in water well.
Chemical Bonding
There are three main types of chemical bonding:
1) Ionic bonding results from the electrostatic attraction between oppositely charged ions. It is characteristic of bonds between metals and nonmetals.
2) Covalent bonding involves the sharing of electron pairs between atoms. It can be polar, nonpolar, single, double or triple.
3) Metallic bonding occurs between metal atoms and involves delocalized valence electrons that are free to move throughout the structure.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
