Answer

Brief Explanations:

Valence electrons are defined as the electrons in the outermost energy level of an atom that are involved in chemical bonding. For nitrogen (atomic number 7), its electron - configuration is 1s²2s²2p³. The electrons in the 2s and 2p orbitals (a total of 5 electrons) are in the outermost shell and are valence electrons.

Answer:

  1. Electrons in the outermost energy level of an atom that are involved in chemical bonding.
  2. 5
