The plutonium isotope with 144 neutrons

Enter the chemical symbol of the isotope.

Plutonium is a radioactive element belonging to the actinide series on the peroidic table. It is located on the f-block.

The isotope of plutonium with a neutron number of 144 can be expressed below:

²³⁸₉₄Pt

238 is the mass number of the isotope

94 is the atomic number

Pt is the symbol of this isotope.

The mass number is the sum of the protons and neutrons in the nucleus of the atom of an element. Here, the number of protons is 94 and it is the same as the number of electrons. Since the given number of neutrons is 144, combining them gives 238 as the value of the mass number.

The atomic number is the number of protons in the atom which is 94.
