Electron outer shell tee hee =^-^=
since the atomic number is 7, and the first full layer takes 8 electrons, it needs 1 electron
Nitrogen (N) has atomic number 7. It has full 1s and 2s orbitals. The 2px orbital has 1 electron, the 2py orbital has 1 electron and the 2pz orbital has 1 electron. So the valence shell is: 2s2 - 2p3. It contains 5 electrons.

it needs six more electrons to have a full outer valence shell.
Since nitrogen is a non-metal with five electrons in its valence shell, it will gain three electrons to attain a stable electronic configuration. So its valency is -3.
the electrons on their outer shell, all atoms want to gain a full valence shell.
Electron outer shell tee hee =^-^=
Valence electrons of any atom are located in the outermost shell that atom carries electrons. For example a carbon atom has 6 electrons: 2e in its first shell (which is full) and 4e (valence electrons) in second shell--there are no electrons farther than second shell for carbon.
Neon is a noble gas, thus It has a full valence shell of eight electrons.
No, only the noble gases in the far right column have a full valence shell.
All eight: the shell is full.
Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
Nitrogen has five valence electrons as a neutral atom, but it is shooting for eight. So it needs to gain three more electrons.
Valence electrons can determine the reactivity of the atom. An atom with a full shell of valence electrons, like neon, will be less reactive than an atom with only one electron in its valence shell, like sodium.
