How many protons, neutrons, and electrons are there in a neutral atom of 131i (iodine-131)?

There are 53 protons, 53 electrons and 78 neutrons in a neutral atom of iodine-131.

Explanation:

Iodine-131 is a radioactive isotope of iodine-127.

An isotope is an atom that has the same atomic number but different weight atomic of its original atom.

- Atomic number = 53

- Atomic weight = 127

- Protons = 53

- Electrons = 53

- Neutrons = Atomic weight - Atomic number = 127 - 53 = 74

- Atomic number = 53

- Atomic weight = 131

- Protons = 53

- Electrons = 53

- Neutrons = Atomic weight - Atomic number = 131 - 53 = 78

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
