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 dissociate into ions when it is placed in water. ...
Water Water is a compound that is made from atoms of hydrogen and oxygen combining with each other. Water is one of our most important resources and is necessary for life. Answer and Explanation: Learn more about this topic: Homogeneous Mixture | Properties & Examples ...
The concept of chemical bonding is normally presented and simplified through two models: the covalent bond and the ionic bond. Expansion of the ideal covalent and ionic models leads chemists to the concepts of electronegativity and polarizability, and thus to the classification of polar and non-...
