Question

The Symbol of nitrogen is 14/7N. Find the number of electrons protons and neutrons in nitrogen​

Answer 1

Answer:

Explanation:

Nitrogen-14 is actually an isotope of nitrogen, so right from the start, you can say that it is a neutral atom.

Isotopes are atoms that have the same number of protons but different numbers of neutrons in the nucleus. You know that nitrogen-14 has 7 protons in the nucleus because it is an isotope of nitrogen, which has an atomic number equal to 7.

Because nitrogen-14 is a neutral atom, the number of protons it has in its nucleus must be equal to the number of electrons that surround its nucleus.

   neutral atom ⇒ no. of protons = no. of electrons

Now, in order to find the number of neutrons present in the nucleus of a nitrogen-14 atom, you must use its mass number. The mass number of an isotope is added to the name of the isotope.

In this case, you have

   nitrogen-14⇒mass number=14

The mass number of an atom tells you the number of protons and neutrons located in the nucleus.

So you can say that

   no. of protons + no. of neutrons=14

This implies that a nitrogen-14 atom contains

   (14.protons + neutrons)−7 protons=7 neutrons

Now, a nitrogen atom, regardless of its mass number, will always form 3− anions, N3−. In other words, any nitrogen atom will take in 3 electrons to complete its octet--this happens because nitrogen is located in group 15 of the Periodic Table.
