What is the general structure of an ionic compound?

a group of two or more atoms sharing electrons
a group of two or more atoms sharing protons
a crystal lattice structure of cations surrounded by atoms
a crystal lattice structure of anions and cations

I think it is A

Let me point out that with no caps and no periods it really is tough to know where one sentence ends and another one starts. Even a souble space between a, b, c, d, would have helpe. Having said all of that I don't think the answer is a.

Would it be a crystal lattice structure of anions and cations since in order to for a crystal you need even amounts of anions and cations

The correct answer is D.

The general structure of an ionic compound is a crystal lattice structure of anions and cations. In an ionic compound, positively charged ions (cations) are surrounded by negatively charged ions (anions), and they are held together by strong electrostatic forces. This crystal lattice structure is what gives ionic compounds their characteristic properties, such as high melting and boiling points, and the ability to conduct electricity when dissolved in water.

The general structure of an ionic compound is a crystal lattice structure of anions and cations. In an ionic compound, the atoms are held together by ionic bonds, which are formed by the transfer of electrons from one atom to another. This transfer results in the formation of positively charged cations and negatively charged anions. The opposite charges of these ions attract each other and arrange themselves in a repeating three-dimensional pattern known as a crystal lattice. So, the correct answer is "a crystal lattice structure of anions and cations" (option D).
