What must react to form ionic compounds?
To form ionic compounds metals must react with non-metals.
Are ions atoms?
Ions are atoms with a charge.
What do most metals form - positive or negative ions?
Metals form positive ions.
What do most non-metals form - positive or negative ions?
Non-metals form negative ions.
The charge on a metal ion is often the same as the group number on the periodic table. True or False?
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.
What ions do transition metals form?
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)
The charge on a non-metal ion is often the same as the group number on the periodic table. True or False?
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)
