Nitrogen ion with a charge of +2 has 7 protons, 7 neutrons, and 5 electrons
Explanation:
To obtain the right answer to the question, we must determine the number of proton, neutron and electron of nitrogen ion. This can be obtained as illustrated follow.
<h3>Step 1:</h3>
Data obtained from the question.
Mass number = 14
Charge = +2
<h3>Step 2:</h3>
Determination of the number of proton.
The atomic number of an element is simply the number of protons in the atom of the element.
Atomic number of nitrogen = 7
Thus, the proton number of nitrogen is 7.
NOTE: The atomic number of an element does not change be it atom or ion, it remains the same.
Therefore the proton number of nitrogen ion is 7
<h3>Step 3:</h3>
Determination of the number of neutron
Mass number = 14
Proton number = 7
<h3>Neutron number =?</h3>
Mass number = Proton + Neutron
14 = 7 + Neutron
Collect like terms
14 – 7 = Neutron
<h3>Neutron = 7</h3>
<h3>Step 4</h3>
Determination of the number of electrons.
Charge = +2
Proton number = 7
<h3>Electron number =?</h3>
Charge = Proton – Electron
+2 = 7 – Electron
Collect like terms
2 – 7 = – Electron
–5 = – Electron
Multiply through by –1
<h3>Electron = 5</h3>
<h3>SUMMARY:</h3>
Nitrogen ion with a charge of +2 has:
1. 7 protons
2. 7 neutrons
3. 5 electrons.
