A nitrogen ion has mass of 14 and charge of +2 which subatomic particles does it contain

A nitrogen ion with a mass of 14 and a charge of +2 contains 7 protons, 7 neutrons, and 5 electrons.

The atomic number of nitrogen is 7, which means that a neutral nitrogen atom contains 7 protons and 7 electrons. However, the nitrogen ion has a charge of +2, which indicates that it has lost 2 electrons. Hence, the nitrogen ion contains 7 protons, 7 neutrons, and 5 electrons.

A nitrogen ion with a charge of +2 is written as N2+. This means that it has lost two electrons.

The atomic number of nitrogen is 7, which indicates that a neutral nitrogen atom has 7 protons and 7 electrons.

Since the nitrogen ion has a +2 charge, it now has 7 protons (as the number of protons does not change) and only 5 electrons (2 electrons less than the neutral atom).

Therefore, a nitrogen ion (N2+) contains 7 protons, 5 electrons, and 7 neutrons.
