Alkaline metal
Very reactive, shiny soft
One valence electron
Example: Li
Alkaline earth metals
Reactive
Two valence electrons
Example: Be
Alkaline earth metals
Reactive
Two valence electrons
Example: Be
Halogen
Gases, very reactive (Br=liquid)
Seven valence electrons
Example: F
Noble gas
Very stable, full valance orbit, gases
Eight valence electrons
Example: Ne
Metalloid
Properties of metals and nonmetals
Number of electrons varies
Example Si
Metal
Conduct electricity, shiny, malleable, form cations
1 to 3 valence electrons
Example : Na
Non-metal
Insulator, brittle, lack lustre (dull) , form, anions
4 to 8 valence electrons
Example: N
What can atoms do to fulfil this happiness in other words, what can they do with their electrons to form a chemical bond?
Transfer or share electrons
Ionic (metal plus nonmetal) compound or transfer electrons
Molecular (2 nonmetals) will share electrons
