Potassium (IPA: /pÉ(Ê)ËtasiÉm/) is a chemical element. It has the symbol K (Arabic: al qaljaâ â Latin: kalium) and atomic number 19 and an atomic mass of 39.098. Calcium (IPA: /ËkalsiÉm/) is the chemical element in the periodic table that has the symbol Ca and atomic number 20.
A calcium ion has 20 protons, the same as its atomic number. The number of electrons depends on the charge on the ion. For the most common calcium ion with a charge of +2, the â¦ number of electrons is 18; 20 - 18 = +2.The number of neutrons depends on the isotope that is ionized and is equal to the mass number of the isotope minus the atomic number of 20. calcium ion has 20 protons, the same as its atomic number.
