Elements are made up of atoms that contain protons, neutrons and electrons. Atoms combine to form compounds made of two or more elements that can be separated through chemical reactions. Chemical reactions involve elements interacting to form new compounds, which can sometimes produce byproducts like gases. A chemical change alters the substances chemically while a physical change only modifies the shape or form. Reaction rates can be affected by factors like temperature, with heat speeding them up and cold slowing them down.

Ix chemistry full notes chapter 1
Matter in our surroundings consists of particles that occupy space and have mass. Solids have a definite shape and volume, liquids have a fixed volume but no definite shape, and gases have neither a definite shape nor volume. The three states of matter - solid, liquid, and gas - differ in their compressibility, with gases being the most compressible and solids the least. A change of state, such as melting or boiling, requires an input of heat energy known as latent heat. The temperature and pressure at which melting, freezing, boiling, and condensation occur depend on the type of substance and can be used to characterize its properties.

Chemistry deals with the properties and structure of matter, as well as changes in matter. There are over 100 known elements, which were formed either during the Big Bang or within stars. Elements combine to form compounds with distinct properties. Matter exists as either pure substances like elements and compounds, or as mixtures of substances. Pure substances cannot be separated into other substances by physical means alone, while mixtures can be separated into their individual parts physically.
Chemistrychapter1 110912173446-phpapp01
This document provides an introduction to chemistry. It begins by defining chemistry as the study of matter and its properties. It then discusses the elements that make up the human body and where elements come from. There are several branches of chemistry including organic, inorganic, physical, analytical, biochemistry, and theoretical chemistry. It also defines key chemistry concepts like matter, elements, compounds, physical and chemical properties and changes. It introduces the three states of matter and phase changes. Finally, it provides an overview of the periodic table, including the development of the periodic table and periodic trends and characteristics of different groups of elements.
Changes of matter
A physical change alters a substance's form or appearance but not its chemical composition, such as water freezing to ice. A chemical change creates new substances through molecular rearrangement, like iron rusting due to oxidation. Chemical changes can be identified by changes in properties such as density, melting point, or reactions producing gas.
Matter
The document summarizes key concepts about matter including:
1. Matter can exist in different physical states such as solids, liquids, and gases which are determined by factors like the strength of attractive forces between particles and their ability to be compressed.
2. Pure substances have a uniform composition throughout while mixtures contain two or more substances and can be either homogeneous or heterogeneous.
3. Elements are substances that cannot be broken down further while compounds contain two or more elements combined in fixed ratios.
4. Metals, nonmetals, and metalloids have distinct physical and chemical properties depending on their position on the periodic table.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Chemical Reactions MB
- 1. Chemistry
- 2. elements An element is a pure substance consisting of only one type of atom. It is distinguished by it’s atomic number, or the number of protons in it’s nucleus.
- 3. atoms An atom is a basic unit of matter. Also it is the smallest recognized division of a chemical element.
- 4. metals A metal is a chemical element, compound or alloy, characterised by high electrical and heat conductivity. It’s also ductile (it can be stretched without breaking) and tensile (it can be bent without breaking).
- 5. non-metals A non-metals (such as hydrogen & carbon) are poor conductors of heat & electricity, and are dull and brittle in solid form. The usually have lower densities, freezing points and boiling points than metals.
- 6. the periodic table The periodic table is a display of all the pure chemical elements. The current standard table contains 117 elements.
- 7. compounds A compound is two or more different elements fused together. Some examples are aluminium, baking soda and tin.
- 8. chemical reactions A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Examples are a plant changing sunlight into energy or metal going rusty.
- 9. identification You can tell if there is a chemical reaction happening because either heat, light, precipitate or gas will be produced.
- 10. Chemical changes A chemical changes is when the bonds of an object are broken and new bonds are formed, creating a new substance (e.g. cooking, corn kernals into popcorn).
- 11. physical changes In a physical change, the substance doesn’t change chemically at all, but takes on a different form (e.g. water freezing and melting)
- 12. reaction rate A reaction rate is the rate that two substances combine to form a chemical reaction. For example, iron rusting is a slow reaction rate. Fire burning a log into charcoal is a fast reaction rate.
- 13. Factors of reaction rate . Concentration – how diluted or pure the substance is. . Temperature – how hot/cold the environment is. . Catalyst – whether or not there is another substance to provide a pathway. . Surface area – powder is going to dissolve faster than a tablet.
