Quantitative Chemistry: Charges on Ions (DONE)

Question 1

What must react to form ionic compounds?

Answer 1

To form ionic compounds metals must react with non-metals.

Question 2

Are ions atoms?

Answer 2

Ions are atoms with a charge.

Question 3

What do most metals form - positive or negative ions?

Answer 3

Metals form positive ions.

Question 4

What do most non-metals form - positive or negative ions?

Answer 4

Non-metals form negative ions.

Question 5

The charge on a metal ion is often the same as the group number on the periodic table. True or False?

Answer 5

Yes, the charge on a metal ion is often the same as the group number on the periodic table.

For example: Na+ is in group 1 and forms a one plus ion, Mg2+ is in group 2 and forms a two plus ion, Al3+ is in group 3 and forms a three plus ion.

Question 6

What ions do transition metals form?

Answer 6

Transition metals can form several different ions.

For example: Fe (iron) can form a Fe2+ ion or a Fe3+ ion. Scientists call this iron (II) and iron (III)

Question 7

The charge on a non-metal ion is often the same as the group number on the periodic table. True or False?

Answer 7

Yes, the charge on a non-metal ion is often the same as the group number on the periodic table.

For example: O2- (group 6), F- (group 7)
