Question

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

Answer 1

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.
