Ca2+
loses 2 electrons to form a calcium ion with 2+ charge
Ca loses electrons. In general metals react in compound by losing some of their electrons, Ca is a metal.
The 19th element is potassium, which has the atomic symbol K. It has 19 electrons, including one valence electron that can be easily lost.
The ionic charge is +2: The atom has equal numbers of positively charged protons and negatively charged electrons. The number of protons is the same in the atom and the ion, but in the ion two negative charges have been lost, so that the ion has a net charge of +2.
it has gain 4 electrons
a calcium ion that has lost two electrons.
The chemical symbol for a magnesium atom that has lost two electrons is Mg2+.
calcium ions that has lost electrons. It will give away electrons.
