Elemental carbon has 6 protons and 6 neutrons. This is often described as carbon-12. Carbon-13 has 6 protons and 7 neutrons, while carbon-14 has 6 protons and 8 neutrons. Based on the trend with carbon and the fact that plutonium has 94 protons, how many neutrons are in radioactive plutonium-244?

Respuesta :

Radioactive Plutonium-244 has 150 Neutrons

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.
