What forces hold network solids together? A. Hydrogen bonds
O B. Covalent bonds
O C. Metallic bonds
D. Ionic bonds

Iknow #2 is d. i just need to know why

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
