Magnesium:
# of valance electrons: 2
Stable? No, it's not stable, it will lose electrons (1, 2, or 3 loses, 4 shares, 5, 6, or 7 will gain) therefore, the charge will be positive

three
2) how many atoms are in the products of the reaction?
36
3) does this equation violate the law of conservation of matter?
no
