Everything that is underlined should get filled in on your notes!
The number of valence electrons increases as you go across the periodic table. When you start each new period, the number of valence electrons drops down to one and begins increasing.
All atoms want a full valence shell (because that is how they become stable!) So, they will share or transfer electrons with other atoms to achieve stability. Nega;ve ions form when atoms gain electrons. Posi;ve ions form when atoms lose electrons.
