This isotope has 20 protons and and electrons and 22 neutrons.
Calcium has 20 protons and electrons and a variable number of neutrons, depending on the isotope.
Potassium has 19 protons, 19 electrons and 20 neutrons.
Chlorine-37 has 17 protons, 17 electrons and 20 neutrons.
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
There are 19 protons,20 neutrons, and 19 electrons.
19 electrons, 19 protons and 20 neutrons
19 protons 19 electrons 20 neutrons
19 protons, 19 electrons, and 20 neutrons
20 protons, 20 electrons, and usually 20 neutrons
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
This isotope has 20 protons and and electrons and 22 neutrons.
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons
