a negative ion
Calcium and bromine have formed a bond. Leading up to this, calcium gave up electrons. It was a(n) ____.
Calcium has electrons in the 4th energy level. The only liquid that has valence electrons in energy level 4 would be BROMINE.
Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).
Remember the talk about the "outer electrons" you learned about? Sodium (Na) has 1 electron in the outer most electron orbital. Calcium (Ca) has, you guessed it, 2 electrons in its' outer most electron orbital. Can you explain the rest to yourself? Remember they had a neutral charge before becoming ionic.
calcium is a metal which ionizes by electron loss,so a calcium ion has lost to electrons and the positive charge indicates electron deficiency.

The element calcium has 20 protons and 20 electrons.
Calcium will lose two electrons to form Ca2+ cation.
Ca2+ and O2-

20 protons and 18 electrons
It gains stability by loosing 2 electrons and acquiring +ve 2 charge....When calcium looses two electrons it attains an octet configuration of the nearest noble gas which is inert due to high stability......
It is Calcium bromide = CaBr2
