What is 1

200

How many valence electrons does Al have?

What is 3

300

How do you figure out valence electrons using the periodic table?

What is group number if less than 10 otherwise digit in ones place

400

How do you use valence electrons to figure out ion charge?

What is more than 4 subtract 8 from valence electrons (negative), less than 4 the charge is the same as valence electrons (positive)

500

What group on the periodic table is most stable and why?

18 because it has a full octet

Grab Bag

100

does Rb make a positive or negative ion?

Positive

200

Why doesn't group 14 generally make ions?

it takes too much energy to gain or lose 4 electrons

300

what is wrong with the name Iodine Potassium

the positive and negative ions are switched and it should end in ide

400

What is wrong with the compound name of Barium Bromine

it should be barium bromide

500

How are ionic bonds formed?

electrons are transfered from a one atom to another, forming a cation and an anion with opposite charges that are attracted to each other
