how many protons neutrons and electrons does ca2 have

by Dr. Katelin Renner II Published 3 years ago Updated 3 years ago

The electron configuration of a Ca2+ ion is: 1s2 2s2 2p6 3s2 3p6, which is isoelectronic with the noble gas argon. Beside above, what is the number of protons neutrons and electrons in calcium? A calcium atom has 20 protons, 20 electrons and 20 neutrons. Calcium's atomic mass is 40.08 g/mole, which rounds to 40 g/mole.

Ca2+ represents an ion with 20 protons and 18 electrons.

What is the number of protons and neutrons in calcium?

11/12/2020 · Calcium is the 20th element, with 20 protons. Since a stable atom has a net charge of 0, we must have 20 electrons. The number of neutrons will be the same as the number of protons: it is also 20. The mass number is 40; The atomic number is 20 (40-20 = 20) Check out the video given below to know more about the size of an atom
