Question

An element has mass number 28 and atomic number 14. Find the number of protons, neutrons, and electrons in it. Write the complete symbol of the element.

Answer 1

Answer:

Protons:14 Electrons:14 Neutrons:14

Explanation:

Atomic no.= no. of protons= no. of electrons= 14;

Mass = no. of protons + no. of neutrons.

∴ No. of neutrons= mass-protons

                            = 14

Answer 2

Answer:

The given is a neutral element.

Thus, atomic no.= no of protons =14

no of protons = no of electron=14

Mass no = no of protons + no of neutrons

no of neutrons = Mass no - no of protons

no of neutrons = 14

Hence, no of neutrons =14

no of protons=14

no of electrons =14
