Further explanation:
The <em>smallest particle</em> that is the <em>building block of matter</em> is known as an<em> atom</em>. Most of the space in an atom is empty, and its <em>mass</em> is concentrated inside a small region called the <em>nucleus</em>.
An atom is written as
, where A is the mass number, Z is the atomic number and X is the letter symbol of the element.
Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. The <em>Protons and neutrons </em>present in an atom are collectively called <em>nucleons</em> because these are located in the nucleus of the atom. Electrons revolve around the nucleus in definite orbits.
The positively charged subatomic particle is called proton. It is equal to the atomic number (Z) of the element.
Electron is the negatively charged subatomic particle. The number of electrons present in an atom is equal to the number of protons of an atom in a neutral atom.
The subatomic particle with no charge is called neutron. It is situated within the nucleus. The number of neutrons present in the nucleus of an atom is called the neutron number. Atomic mass or mass number is the total number of nucleons within the atomic nucleus. So if the atomic number or the proton number is known, the number of neutrons can be calculated by the difference of mass number (A) and atomic number (Z).
Given element is
. By comparing it with the general representation of an atom
, it is clear that the given atom carbon has atomic number 6 and mass number 13.
As we know, the number of protons is equal to the atomic number of the element. So number of protons in
is 6.
The number of electrons is equal to number of protons in a neutral atom. So number of electrons in
is also 6.
The number of neutrons present in the carbon atom can be calculated as follows:
Number of neutrons = Mass number (A) –Atomic number (Z)
Substitute 13 for mass number and 6 for the atomic number in the above equation, we get:
So the number of protons, electrons, and neutrons in
are 6, 6, and 7 respectively.
