Magnesium oxide is an ionic compound with a very high melting point and which requires a large amount of energy for melting.

<h3>What are ionic compounds?</h3>

Ionic compounds are compounds which are formed between oppositely charged ions which are held together by electrostatic forces of attraction between the oppositely charged ions.

Ionic compounds are formed when metal atoms donate electrons to non-metals atoms to form ions.

Magnesium oxide is an ionic compound.

The nature of bonding is ionic bonding.

It has a crystalline lattice structure.

The forces of attraction is electrostatic forces of attraction.

It has a high melting point of 2,852 °C, and thus requires a large amount of energy go melting to occur.

Therefore, magnesium oxide is an ionic compound which requires a large amount of energy for melting.

How does the formal charge play a role in resonance?
Crank
In a Lewis structure, formal charges can be assigned to each atom by treating each bond as if one-half of the electrons are assigned to each atom. ... Resonance occurs in cases where two or more Lewis structures with identical arrangements of atoms but different distributions of electrons can be written.

What part of the atom determines if it will combine or break apart from other substances
enyata [817]

The combination of an atom with other atom is bonding. Or break apart from other substance is breaking of interaction.

The bonding or interaction (inter-atomic) are due orbitals and electrons present in these orbitals

The atom consists of

a) a central nucleus which has proton and neutrons: they do not take part in chemical reactions

b) the part other than nucleus which has shells, sub shells and orbitals

These orbitals have electrons.

So the outer part of nucleus takes part in any combination with other substance
