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).

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
