Question

can we find the number of neutrons present in an atom if protons, atomic number and electrons are given plzzz answer fast urgent

Answer 1

You can simply subtract the atomic number from the mass number in order to find the number of neutrons. If the atom is neutral, the number of electrons will be equal to the number of protons. 1.

Answer 2

The Atomic Number is denoted by 'Z'.
The Atomic Mass is denoted by 'A'.
Here protons are denoted by 'P'.

To find number of Neutrons in an atom we see a example,

Example: Refer the attachment.
Nber of Neutrons
=Atomic mass-Number of protons/electrons.
=A - Z.
