The electronegativity of an element is a measure of how strongly it attracts electrons in a covalent bond. Electronegativity increases left to right and top to bottom in a period, and metals have the lowest values while nonmetals have the highest. The difference in electronegativity between two bonded atoms indicates bond type - ionic bonds form when difference is >1.7, covalent bonds form when difference is <1.7, and polar covalent bonds form for differences in between. Electronegativity values can be used to predict and investigate bond types.

Polar and nonpolar bonds and polar molecules970245
polar and nonpolar bonds are explained with example and practice work is also given diplole action is explained. polar and non-polar molecules explained.
✔Here is an introduction to the Chemistry of Life, where you will learn about Ionic, Covalent and Metallic bonds. This presentation touches briefly, but it covers the definition of three major types of chemical bonds: ionic, covalent, and metallic. Ionic bonds form due to the transfer of an electron from one atom to another. Covalent bonds involve the sharing of electrons between two atoms. Metallic bonds are formed by the attraction between metal ions and delocalized, or "free" electrons.✔

Determine whether the bond between each of the following pairs of atom.docxandyb37
Determine whether the bond between each of the following pairs of atoms is purely covalent, polar covalent, or ionic.
1. O and O
2. Li and O
3. C and N
4. N and S
Solution
Pure covalent bond- when both the participating atoms are having same electronegativity value (i.e- for homonuclear molecules) Exp - O and O
polar covalent bond- both particiapting atoms share equal number of electrons to form coavalent bond, however, the shared electron pair remains more towards the more electronegative atoms.
Exp- C and N (electronegativity of N is more than C, the share electron pair remains towards the nitrogen. carbon bears partial positive charge and nitrogen bears partial negative charge)
N and S (electronegativity of N is more than S, the share electron pair remains towards the nitrogen. sulfur bears partial positive charge and nitrogen bears partial negative charge)
Ionic bond - one atom is highly electronegative and the other atom is highly electropositive
EXp- Li and O

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

GraphRAG is All You need? LLM & Knowledge GraphGuy Korland
Guy Korland, CEO and Co-founder of FalkorDB, will review two articles on the integration of language models with knowledge graphs.
1. Unifying Large Language Models and Knowledge Graphs: A Roadmap.
https://arxiv.org/abs/2306.08302
2. Microsoft Research's GraphRAG paper and a review paper on various uses of knowledge graphs:
https://www.microsoft.com/en-us/research/blog/graphrag-unlocking-llm-discovery-on-narrative-private-data/
2. Trends across the periodic table
Electronegativity increases from left to right
across the periodic table as the number of
valence electrons increase
Electronegativity values decrease from the top to
the bottom in any group as the atomic radii
increases
Metals are the least electronegative elements,
while non-metals are the most electronegative
4. Electronegativity gives an
indication of bond type
The bigger the difference in
electronegativity the more ionic
the bond is.
5. Electronegativity values can be
used to predict bond types
A difference in electronegativity between two
atoms of >1.7 indicates that the bond is ionic
A difference in electronegativity between two
atoms of <1.7 indicates that the bond is
covalent
Polar Covalent: An uneven share of electrons.
Electronegativity difference of more than
zero but less than 1.7
6. 100% covalent compounds
100% covalent compounds have a
electronegativity value of zero.
This generally only happens when they are
the same element. e.g. F and F

7. Bond Polarity and Electronegativity
Electronegativity and Bond Polarity
• There is no sharp distinction between bonding types.
• The positive end (or pole) in a polar bond is represented δ
+ and the negative pole δ-.
HyperChem
8. Example
H and F
Hydrogen has a electronegativity value of
2.1. Fluorine has a electronegativity of 4.0.
The difference between them is 1.9
=> Ionic in character
9. Investigate the bond type
between the following atoms
Which of the following compounds are ionic, fully covalent or polar
covalent?
H and F
H and S
H and N
C and O
H and H
Cl and Cl
