When electrons transfer from one atom to another, both atoms become Choose... and they are held together by a(n) Choose... bond. When electrons are shared between atoms, a(n) Choose... bond forms between the atoms, and the joined atoms become a(n) Choose... .

This question is incomplete as it lacks a word bank, the word bank are:

Covalent

Negative

Ionic

Ionic compound

The answer is:

1. Ions

2. Ionic

3. Covalent

4. Molecule

Explanation:

An ION is a charged atom i.e. an atom with positive (+) or negative (-) charge, which results when an atom loses or gains electrons respectively. The ions of different elements are held together by bonds called IONIC BONDS, which are bonds that form as a result of the difference in electric charges or electrostatic forces between the atoms involved. For example, an ionic bond forms between NaCl because there is an electrostatic force between the positive Na+ ions and negative Cl- ions.

However, on the contrary, when electrons are shared between atoms, a COVALENT BOND is formed. The atoms share their valence electrons to form a MOLECULE, which comprises of two atoms.

the correct answer is 2 and 4
