0
Q
Describe cations and their relationship with the neutral atom
A
They are formed when an atom loses electrons, they are smaller than the neutral atom because they feel more attraction because the protons outnumber the valence electrons
1
Q
What is an ion?
A
An atom with a charge
2
Q
Describe anions and their relationship with the neutral atom
A
They are the atoms that gain electrons, they are bigger than the neutral atom because there are more valence electrons than protons and they repel each other
