Question

The atomic number and mass number of an element 'P' are 23 and 47, respectively. How many neutrons are present in the atom?

Answer 1

Answer:

24 Neutron present in the element P

Explanation:

As in the question given that Element 'P' had the atomic no. 23 and mass no. 47.

We all know that Atomic no. = No. of Protons present in an atom and Mass no. = No. of Protons + No. of Neutron.

Thus, atomic no. is 23 so Protons are also 23. So we get the Protons so set the equation

Let the neutron be N

Mass no. = No. of Protons+No.of Neutrons

47 = 23 + N

N = 47 - 23

N = 24

There 24 Neutron is present in the atom 'P'
