Based on the definition provided in the text regarding valence, if an atom requires 2 electrons to fill its valence shell, how many covalent bonds can it typically form?

  • A: 1 bond
  • B: 2 bonds
  • C: 3 bonds
  • D: 4 bonds

Explanation

The text states: "Valence, the number of covalent bonds an atom can form, is generally equal to the number of electrons required to fill the valence shell." If an atom needs 2 electrons to fill its valence shell, its valence is 2, meaning it can typically form 2 covalent bonds.
