Calcium and Oxygen are the atoms in Calcium Oxide.
Calcium chloride is a salt; calcium is the cation and chloride the anion.
The chemical formula starts out with the two ions, the calcium and sulfide ions. Calcium's ion is Ca2+, while the sulfide ion is S2-. Because the net ionic charge of a compound is zero, only one of each atom is needed to create calcium sulfide, which will be CaS.
The cation in lithium sulfide is Li+, which is the lithium ion. The anion in lithium sulfide is S2-, which is the sulfide ion.
The ionic bond formula between calcium and sulfur is CaS, where calcium loses 2 electrons to form Ca2+ cation and sulfur gains 2 electrons to form S2- anion. This results in the formation of an ionic compound called calcium sulfide.
Calcium and Oxygen are the atoms in Calcium Oxide.
The charge on the cation in barium sulfide is +2, as barium is in Group 2 of the periodic table and typically forms cations with a 2+ charge.
As the elemental metal, calcium is neither a cation nor an anion. Its elemental symbol is 'Ca(s)' . 's' indicating that it is solid. However, like sodium , calcium readily ionises ( loses) 2(two) electrons. Symbolically it is now 'Ca^(2+) ' . It is an ION. Because it is a positive(+) ion , it is known as a 'CATION'. Compare to chlorine, it has electron affinity, and symbolically it is ' Cl^(-) ' . It is also an ION. But because it is a negative (-) ion , it is known as an ANION. So remember. any atom that loses or gains electrons, is no longer an atom, but an ION. If the ion is positively(+) charged, then it is a CATION , and if the ion is negatively(-) charged , then it is an ANION.
Calcium chloride is a salt; calcium is the cation and chloride the anion.
Calcium becomes the cation in calcium chloride. As a metal, calcium loses two electrons to achieve a full valence shell, acquiring a +2 charge to become a cation.
The chemical formula starts out with the two ions, the calcium and sulfide ions. Calcium's ion is Ca2+, while the sulfide ion is S2-. Because the net ionic charge of a compound is zero, only one of each atom is needed to create calcium sulfide, which will be CaS.
The element is calcium and the cation is Ca2+ ion
The calcium cation is (Ca)2+.
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
The cation in lithium sulfide is Li+, which is the lithium ion. The anion in lithium sulfide is S2-, which is the sulfide ion.
Sodiumis in group 1 and its cation is charge +1. Calcium is in group 2 and the cahrge on its cation is +2. etc.
The ionic bond formula between calcium and sulfur is CaS, where calcium loses 2 electrons to form Ca2+ cation and sulfur gains 2 electrons to form S2- anion. This results in the formation of an ionic compound called calcium sulfide.
