Question

The atom of an element has $20$ protons, $20$ neu­trons, and $20$ electrons. Find out the name of the element

Answer 1

Given:

Number of protons$=20$

Number of neutrons$=20$

Number of electrons$=20$

Formula used:

Atomic number$=$Number of protons$=$Number of electrons

Find the atomic number of the element:

Atomic number$=$Number of protons$=$Number of electrons

Thus, the atomic number of the element is $20$.

Find the name of the element:

The atomic number of the element is $20$.

The element with atomic number $20$ is Calcium $\left(\mathrm{Ca}\right)$.

Thus, the name of the element is Calcium $\left(\mathrm{Ca}\right)$.
