An element from Group 2 will form ionic bonds with a nonmetal, Groups 13-17

Explanation:

An ionic bond is formed between a "metal and non-metal". The valence electrons are lost in one and gained in the other atom. It involves electrostatic forces between the two ions which are of opposite charges.  

When one atom(metal) losses an electron, it becomes a "positive ion". Similarly, when the other atom(non-metal) gains an electron it becomes a negative ion. For example: The formation of NaF(Sodium Fluoride).

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

the answer is minerals.
