i think it's KOBALTOUS :D
The electrical charge of cobalt is 2+.
All atoms (other than Noble Gases) can become ions, and all ions are charged. Cobalt gains a charge of +2 as an ion.
The molecular formula is CoO Cation is Co^2+^Anion is O^2-^or in other wordscobalt(II) oxide = CoO = Co2+ + O2-
The core notation for the electron configuration of a cobalt 2 ion is [Ar] 3d7. The [Ar] represents the electron configuration of the argon noble gas, which has the electron configuration 1s2 2s2 2p6 3s2 3p6. The 3d7 indicates that there are seven electrons in the 3d subshell of the cobalt ion.
The valence of cobalt, in this case 2; Cobalt (II) phosphate.
cobalt II perchlorate is an ionic compond cobalt II has an oxidation number of +2; its symbol is Co perchlorate is a polyatomic ion with a charge of -1; its formula is ClO4 therefore the formula is Co(ClO4)2
name of zinc ion is chemistry is Zn +2.It has valency of 2 electrons.
The neutral atom of cobalt has 27 electrons. The number can vary up or down depending on the chemistry of the sample of cobalt. A link is provided to the Wikipedia article on the element cobalt.
Co(BrO3)2 would be named cobalt(II) bromate
Strontium Ion
The name of the compound is cobalt(II) chloride. It is made up of the elements cobalt and chlorine. The anhydrous form of the compound is sky blue, while the hydrated variant, its hexahydrate (CoCl2·6H2O), is deep purple.
Cobalt nitrate.
