An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions. 1. Compounds between metal and nonmetal elements are usually ionic. 2. If you recognize the formula of a polyatomic ion in a compound, the compound is ionic. (Groups of atoms with an overall ...
(c) An ionic bond involves a metal that shares electrons with a nonmetal (d) The difference between an ionic bond and a covalent bond is that: a) ionic bonds commonly occur between two metals and covalent bonds occur between metals and nonmetals. ...
The only pure covalent bonds occur between identical atoms. Usually, there is some polarity (polar covalent bond) in which the electrons are shared, but spend more time with one atom than the other. Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals....
No, the ionic bond can not form between two metals. An ionic bond is formed between positive and negative ions or a metal and a non-metal by the donation of electrons. Q8 How are ionic bonds formed between atoms? Ionic bonds are formed by the complete transfer of electrons between two...
An ionic bond forms between a nonmetal and a metal in which the nonmetal attracts the electron from the other atom. Ionic bonds are high in polarity, have no definite shape and have high melting and boiling points. At room temperature, an ionic bond is a solid. An ionic compound tends to...
