Example 1

easy
How does a covalent bond form in a hydrogen molecule (H2\text{H}_2)?

Solution

  1. 1
    Each hydrogen atom has 1 valence electron and needs 1 more to fill its 1s1s shell.
  2. 2
    Two H atoms share their electrons, forming a single covalent bond: H–H\text{H–H}.
  3. 3
    Each atom now effectively has 2 electrons, achieving the helium configuration.

Answer

H:H or H–H (single covalent bond)\text{H:H or H–H (single covalent bond)}
Covalent bonds form when nonmetal atoms share electrons to achieve stable electron configurations. The shared pair is attracted to both nuclei, holding the atoms together.

About Covalent Bond

A chemical bond formed when two atoms share one or more pairs of valence electrons, creating a strong attractive force that holds them together as.
