Nitrogen would have a neutral charge and eight valence electrons.
The charge an element would have if it lost or gained electrons
The protons have a positive charge and the electrons have a negative charge, so it would be 7 + -5, so the charge is +2.
If the 7 protons and 7 neutrons are in the nucleus of an atom, and the 9 electrons are in the electron cloud surrounding the nucleus, then yes, this would represent an ion with a 2- charge. And, in looking at the periodic table, this would be a nitrogen atom with a 2- charge, which is hypothetical, since nitrogen atoms gain 3 electrons when forming ions, and would therefore actually have 10 electrons, and a charge of 3- . However, the important thing is that if an atom has an unequal number of protons and electrons, it is an ion.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
Each electron has a 1- charge, so an atom that has gained 5 electrons has a charge of 5-.
Such an atom would be neutral - no electric charge.
When "x" valence electrons are lost the charge is +x When "x" valence electrons are gained the charge is -x for example, if chlorine gained one electron, the charge would be Cl 1- or, if magnesium lost two electrons, the charge would be Mg 2+
The charge an element would have if it lost or gained electrons
The answer would be ion :D
If you mean an atom, if it gains electrons it becomes more negative, so a negative charge. If you really mean an ion, it depends on the charge of the ion.
The protons have a positive charge and the electrons have a negative charge, so it would be 7 + -5, so the charge is +2.
There are often 7 electrons in nitrogen except when the nitrogen is in its ion form; then it would have 10 electrons.

Elemental nitrogen has no charge., but as an ion it can have a charge that depends on how many electrons it has captured or released.In compounds it can have oxidation states of +5, +4, +3, +2, +1, −1, −2, −3In ammonia (NH3) and ammonium ions (NH4+) it has a oxidation value of -3 (and actually only a partial negative charge as part from a polar covalent, non-ionic bond).In Nitrate (NO3-) its oxidation value is +5, in nitrite +3 (but only a partial positve charge in both)
