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.
When a calcium atom loses two electrons, it is still a calcium atom. However, the charge goes up by 2.
It'd be Ca2+, because now the number of protons (which rarely changes) is greater than the number of electrons by 2.
calcium looses its two electrons to become stable
Usually calcium loses 2 electrons, that's why calcium is found in Group 2 of the periodic table.
Like all metals calcium will lose electrons.
I believe it is 2, seeing it is a metal, and has 2 valence electrons. Correct me if I'm wrong, I don't have my periodic table with me (Calcium -> Ca?).
Ca must lose 2 electrons to have a complete 3n shell, which has 8 valence electrons. The ion would have a charge of 2+: Ca^2+.
calcium has 20 electrons.when it loses 2 electrons, it has 18 electrons.
Usually calcium loses 2 electrons, that's why calcium is found in Group 2 of the periodic table.
calcium loses two electrons, becoming a +2 ion
A calcium ion (Ca2+) loses two electrons from an atom to achieve a stable octet electron configuration. This results in a +2 charge on the calcium ion.
Calcium has 2 valence electrons and it typically loses these 2 electrons to achieve a stable configuration.
2 electrons as it has 2 valence electrons, hence it has a tendency to lose 2 electrons to achieve noble gas configuration
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
Metals always lose electrons.
Like all metals calcium will lose electrons.
I am not sure what you mean by atoms, i think you mean electrons (part of an atom).Calcium is in Group 2 of the periodic table so this means that in order to become stable it will lose 2 electrons.
I believe it is 2, seeing it is a metal, and has 2 valence electrons. Correct me if I'm wrong, I don't have my periodic table with me (Calcium -> Ca?).
Calcium is more likely to lose electrons because it has two electrons in its outermost shell, making it easier for calcium to achieve a stable electron configuration by losing these two electrons to become a positively charged ion.
Calcium has to lose 2 electrons to form noble gas configuration.
