$100 Question from H1 How many valence electrons does an atom want to have?

$100 Answer from H1 8

$200 Question from H1 Noble gasses have how many electrons and what charge?

$200 Answer from H1 8 valence electrons, no charge

$300 Question from H1 Sulfur has how many valence electrons and it’s ions have what charge?

$300 Answer from H1 6, -2

$400 Question from H1 Alkaline Earth Metals have how many valence electrons and what charge?

$400 Answer from H1 2, +2

$500 Question from H1 What happens to the atom radius of an atom when it loses an electron and why (be specific)?

$500 Answer from H1 The radius becomes smaller because - Each electron is attracted more strongly to the positive nucleus (protons) -The positive charge of the nucleus is divided among more electrons No change in electron shell!
