radioactivity

reactivity

conductivity

electronegativity

Some bonds are covalent.

Some bonds are ionic.

All bonds involve some degree of sharing.

All bonds are either totally ionic or totally covalent.

increased number

decreased number

similar number

There are more neutrons the further right you go.

There are more protons the further right you go.

There are more electrons the further right you go.

Valence electrons are attracted to nucleus and shielded by more energy levels.

Valence electrons are attracted to more energy levels and shielded by the nucleus
