how many valence electrons are shared, gained, or lost in nitrogen?

N has atomic number of 7 so it has 7 protons and 7 electrons. Electron configuration is 1s2 2s2 2p3. Say 3 or 5?

To determine the number of valence electrons shared, gained, or lost in an atom, you first need to know the electron configuration of the element. Nitrogen, which has an atomic number of 7, has the electron configuration of 1s² 2s² 2p³. This means nitrogen has 5 valence electrons.

To calculate whether nitrogen shares, gains, or loses electrons, you need to consider its position on the periodic table. Nitrogen is located in Group 15 (also known as Group V) of the periodic table, which means it tends to gain 3 electrons to achieve a stable octet (eight valence electrons).

Since nitrogen starts with 5 valence electrons and wants to gain 3 more electrons to complete its octet, it will gain electrons. Therefore, in nitrogen, 3 valence electrons will be gained.

To summarize, nitrogen gains 3 valence electrons.
