Question

Is it possible for the atom of an element to have one electron one proton and no neutron,?if so name the element.

Answer 1

Hydrogen is the element which has one electron one proton and no neutron.

Explanation:

• Hydrogen is the first element in the periodic table with mass number 1.008 and atomic number 1.
• The atomic number of the elements is equal to the number of protons present in the atom of the element.
• As the atomic number of hydrogen is 1, it infers that hydrogen contains 1 proton.
• In an atom number of protons = number of electron. Thus as hydrogen has 1 proton, it contains 1 electron.
• When the value of neutron in hydrogen is calculated using the following formula, it gives

Mass number = No. of protons + No. of neutrons.

Mass number - No. of protons = No. of neutrons

1.00 - 1 = 0

• Thus the above calculation infers that hydrogen has 0 neutrons.
