Alkali metals , alkaline earth metals and halogens are most important ionic compound former .
Ionic bonding forms compounds.
No: sodium forms a positive ion in its ionic compounds.
Carbon normally forms four covalent bonds in its compounds, not ionic bonds.
Cerium typically forms ionic bonds rather than covalent bonds. In its compounds, cerium usually forms the +3 oxidation state, where it loses three electrons to form ionic bonds with other elements.
Calcium typically forms ionic compounds, as it readily loses two electrons to achieve a stable electron configuration. In ionic compounds, calcium forms a cation with a 2+ charge.
chlorine forms ionic compounds with metals and covalent compounds with non-metals.
Sodium and magnesium are both ionic elements. Sodium forms a +1 cation, and magnesium forms a +2 cation when they lose electrons, resulting in the formation of ionic compounds when they react with non-metallic elements.
MoCL6 is not an ionic compound. Mo is a transition metal which often forms covalent compounds rather than ionic compounds.
Bromine (Br) All nonmetals except the noble gasses will react with lithium to form ionic compounds.
Type 1 binary ionic compounds are those in which the cation has only one form, or charge. Type 2 binary ionic compounds are those in which the cation can have multiple forms.
pay attention
Rubidium (an alkali metal) does not form compounds or ionic bonds with calcium (an alkaline earth metal). The two each form compounds with several of the same elements (e.g. chloride, carbonate, nitrate).
