Answer 2

Helium and Carbon are two elements with same number of protons and neutrons.

Number of protons and neutrons in Helium:

• To calculate the number of protons and neutrons, the following data is essential:

Atomic number of helium = 2

Mass number of helium = 4

• As the atomic number is equal to the number of protons, therefore the number of protons present in helium is 2.
• As number of neutron = Number of protons - Mass number = 2-2 = 4.
• Thus Helium has 2 protons and 2 neutrons.

Number of protons and neutrons in carbon:

Atomic number of carbon = 6

Mass number of carbon = 12

• As the atomic number is equal to the number of protons, therefore the number of protons present in carbon is 6.
• As number of neutron = Number of protons - Mass number = 6-12 = 6.
• Thus carbon has 6protons and 6 neutrons.
