How many protons neutrons and electrons in bismuth 210?

Answer 1

The chemical element, bismuth, has an atomic number of 83. That means that, assuming it's electrically neutral, it has 83 protons and 83 electrons. Since we know that this particular isotope of bismuth has a combined total of 205 protons and neutrons, the total number of subatomic particles in 205Bi; i.e., the total number of protons, neutrons, and electrons, is 205 + 83 = 288.

Answer 2

Bismuth subatomic particles = 208.98 + 83 = 291.98

because there are 83 protons and 208.98 equals mass number.

Answer 3

209 subatomic particles (83 protons, 126 neutrons)

Answer 4

Protons-83

Electrons-83

Neutrons-127
