Multiple Select
What is a cation?
a neutral ion
an atom with a positive charge
and atom with a negative charge

Multiple Select
What is a anion?
a neutral ion
an atom with a negative charge
and atom with a positive charge
an atom that has lost electrons
an atom that has gained electrons
5
Why do elements gain or lose electrons?
6
Octet Rule
Electrons are lost or gained to have an electron configuration like the noble gas (pseudo-isoelectric).
Want a valence electrons shell of 8 electrons
Some text here about the topic of discussion
7
Less than 4 valence electrons (metals) lose electrons --> cation
More that 4 valence electrons (nonmetals) gain electrons --> anion
Some text here about the topic of discussion.
