Which of the following are likely to form a covalent bond?
two gold atoms
o two neon atoms
• hydrogen and oxygen ·atoms
magnesium and bromine atoms

• Hydrogen and oxygen atoms  

Explanation:

Hydrogen and oxygen are nonmetals. They are most likely to share electrons and form a covalent bond.

A is wrong. Gold is a metal, so it will form metallic bonds.

O is wrong. Neon is a noble gas. It has a complete octet, so it is unlikely to form covalent bonds.

D is wrong. Mg is a metal, and Br is a nonmetal. They are more likely to form ionic bonds.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
