Sodium. A sodium atom has one valence electron in its 3rd energy level. This is very unstable, so a sodium atom will lose that single valence electron to another atom (nonmetal), and the 2nd energy level will then have 8 valence electrons, which is stable. The positively charged sodium ion, Na+, will bond with a negatively charged ion; either a nonmetal or a polyatomic ion.
calcium
Nitrogen
This chemical element is calcium (Ca).
Nitrogen
It was not invented. Chlorine is a natural chemical element like oxygen or nitrogen.
You don't. Calcium is not an electron, calcium is a element
Calcium is a Metal.
Calcium, Chlorine and Oxygen
Calcium is a metal element while chlorine is a non metal. The difference between the electron negativities of the elements is more than 2.1. So they form ionic bonds.
Farogen is not an elemnt known to science. The element that can use one electron is chlorine, which achieves the octete when it gains an electron. hydrogen becomes the hydride ion with a stabel duet (He configutaration) Sodium can lose one electron to acheive the octet.
Chlorine reacts readily with calcium. Calcium donates two electrons to this ionic bond and chlorine accepts one electron from calcium into its valance shell, so you need two chlorines to react with calcium. Ca(2+) and Cl- = CaCl2 Calcium chloride
calcium
Calcium chloride contain calcium and chlorine.
Nitrogen
Chlorine
yes, chlorine is a diatomic molecule, meaning two chlorine atoms can combine together to form a molecule.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
