Atomic Bonding and Octet Rule

Electronegativity

A measure of the tendency of an atom to attract a bonding pair of electrons. It is a key concept in understanding chemical bonds and molecular interactions.

Noble Gass _______ electronegativity values

Dont have

Why do Nobles gasses not have electronegativity values

because they have a full valence shell and do not readily form bonds.

Ionic bonding

A type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically involving the transfer of electrons from one atom to another.

Metallic Bonding

A type of chemical bond that occurs between metal atoms, characterized by a sea of delocalized electrons that allows for conductivity and malleability.

Covalent Bonding

A type of chemical bond formed when two atoms share one or more pairs of electrons, typically occurring between nonmetals.

Ionic substances are made of __________ arrays of 4 positive and negative ions

Repeating

Ionic Compounds have ______ melting and boiling points

High

Ionic compounds are _______ Souble in water

Highly

Ionic compounds are ______ at room temp

Solids

Ionic Compounds are ______ (Strong / Brittle / Malleable)

Brittle

good

In metals, the valence electrons are _____ to move throughout the metallic structure

free

elctrons in metallic bonding are referred to as:

sea of delocalized atoms

good

the ____ of the metallic bond depend on:

1. the charge

2. the ionic radius

3. the melting pointC

strength

Covalent bonds form when atoms ______ electrons

share
