Answer;
= 150 neutrons
Explanation;
- An atom of an element is made of subatomic particles, namely; protons, neutrons and electrons. Neutrons and protons are found in the nucleus of an atom while electrons are found in the energy shells of the atom.
- The atomic number is the number of protons in the nucleus of an atom while the sum of protons an neutrons gives the mass number.
- The mass number of isotopes of a given element such as carbon is different as a result of different number of neutrons in their nucleus.
- In polonium-244, the mass number is 244, and the number of protons is 94, therefore the number of neutrons will be 150 or the number of protons subtracted from the mass number.
