Given:
No. of protons = 8
No. of Neutrons = 9
No. of electrons = 8
To find:
Atomic mass =?
Formula to be used:
Atomic mass = No. of protons + No. of Neutrons
Answer:
Atomic mass = No. of protons + No. of Neutrons
Atomic mass = 8 + 9
Atomic mass = 11
Explanation:
Atom is composed of three subatomic particles namely proton, electron, and neutron. The composition of these sub atomic particles is used to calculate the atomic mass.
The atomic mass of the element is nothing but the sum up value of the total number of protons and neutrons present in the nucleus of the atom of the element.
According to the given data, the atomic mass of the element with 8 protons and 9 neutrons is found as 11.
