What bond would LiBr be ?

If it’s covalent, would it be polar or non polar ?

1. What bond would LiBr be ?

Ionic bond

In order to attain stability, lithium (Li+) donates one electron to bromine (Br-) and forms an ionic bond. It is a molecular compound.

2. In a covalent bond it will hold onto electrons more tightly. For a bond to be polar, the electronegativity difference between the two elements needs to be between 0.5 to 1.6. If the electronegativity difference is less than 0.5, the bond is nonpolar.

the answer is barium and copper bromide
