Question

Write a brief passage describing a neutral atom of nitrogen-14 (N-14). Describe the number of protons, neutrons, and electrons in the atom, where each type of particle is located, and how the terms atomic number, mass number, and atomic mass are related to the particles. Use the periodic table to help you.

Answer 1

Answer: This element has 7 protons, 7 electrons and 7 neutrons.

Step-by-step explanation:

There are 3 subatomic particles present in an atom. They are: protons, electrons and neutrons.

• Protons: They carry positive charger and are present in nucleus.
• Electrons: They carry negative charge and are present around the nucleus.
• Neutrons: They dos not carry any charge and are present in nucleus.

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

Atomic mass is the sum of masses of each isotope each multiplied by their natural fractional abundance. This is also related to protons and neutrons present in an atom.

We are given:

An element having formula
`_7^(14)\textrm{N}`

Atomic number = Number of electrons = Number of protons = 7

Mass number = 14

Number of neutrons = 14 - 7 = 7

Atomic mass of nitrogen = 14.01 amu

Hence, the given element has 7 protons, 7 electrons and 7 neutrons.

Answer 2

In nitrogen-14, there are 7 protons, 7 neutrons, and 7 electrons. The protons and neutrons are in the nucleus, and the electrons are in the electron shells. The atomic number is the number of protons, the mass number is the number of protons AND neutrons, and the atomic mass is the average of the masses of all isotopes.
