Why do chemical bonds form?
so the number of protons equals the number of electrons
to fill the outermost electron level
so an atom can become unstable
An electron has a ___ charge.
no charge
positive

The chemical bond formed when two atoms share electrons is call a(n)
covalent bond
ionic bond
metallic bond
electron bond
An ionic bond is formed when
Valence electrons are shared.
Valence electrons surround the cations.
Valence electrons are transferred between atoms.
Valence electrons are completely transferred between two metals.
Cations are ions with _________ charge.
positive
negative
gains
loses
An atom with 1 valence electron 'needs' a full shell, so it can either gain 7 electrons or lose 1. Which is more likely to occur?
nothing
gain 7
lose 1
The reason that Noble Gases do not react is because
Their outer electron shell is filled
Their inner electron shell is filled
They are able to bond to fill their outer shell
None of the above, Noble Gases are highly reactive
This refers to the tendency of atoms to prefer to have eight electrons in the valence shell
