A metal and a nonmetal will generally combine to form an ionic compound.
calcium chloride,chromium (III) bromide
K is an element. It is elemental Potassium metal.
Be3P2 Is an ionic compound made up of the group II metal beryllium, a cation is this compound and the nonmetal phosphorus, an anion is this compound. Be 2+ and P 3- combine ionicly to form Be3P2
Members of groups 1, 2, 6, 7 in the Periodic Table are most likely to form ionic compounds. It depends on what pair of elements are involved, for instance one rule of thumb is metal with nonmetal. Another, more systematic way, to assess this is to consider the difference in electronegativity between the two elements. If the electronegativity difference is 2 or more then the bond will be ionic. If the difference is less than 2 but more than 1.6 and one of the elements is a metal then there can be an ionic bond.
Molecule if there is some sharing of electrons or an ionic compound if there is a donation of an electron from one atom to another.
I'm not sure, but I think you are asking ... you break down a compound into elements. E.g., water is a compound, two part Hydrogen, one part Oxygen. Oxygen and Hydrogen can both be found on the elemental chart.
Ca2+ + 2 I- --> CaI2
K is an element. It is elemental Potassium metal.
compound or solution. he could be talking about a covalent or ionic bond
Be3P2 Is an ionic compound made up of the group II metal beryllium, a cation is this compound and the nonmetal phosphorus, an anion is this compound. Be 2+ and P 3- combine ionicly to form Be3P2
Ca2+ + 2 I- --> CaI2

When these two elements form an ionic compound (either with each other or with any other elements) then those are the ions that they form, Ca+2 and F-1.

MgF2 Magnesium, an alkaline earth metal of 2+ ionic charge and two fluorine, a nonmetal, atoms of 1- charge each form a ionic bond
