This type of chemical bond generates two oppositely charged ions. In ionic bonding, the metal loses electrons, becoming positively charged, while the nonmetal gains electrons (lost by the metal), becoming positively charged. Therefore, the metal atom is known as an electron donor, and the nonmetal atom is known as the electron acceptor. Atoms that participate in ionic bonding have different electronegative values from each other.  \nA covalent bond is the sharing of electrons between atoms, usually nonmetals, but can also occur between nonmetals and metals. This bond is usually present between two atoms of the same element or elements close to each other in the periodic table. Covalent bonds favor elements with similar electronegativity since neither element would choose to donate their electrons, a sharing of electrons would occur.  \nDot-and-Cross Diagrams: Show the ionic bonds between ions by the loss and gain of electrons, and, the covalent bonds between atoms, by the sharing of electrons.  \n􀁸 Only the outer shell of electrons of each atom is drawn  \n􀁸 Electrons in one atom will be represented as crosses, whilst electrons in the other atom will be represented as circles, indicating which ion gains or loses electrons  \n􀁸 For ionic bonds, the charge of each ion is displayed at the upper right corner of each ion.  \n􀁸 For covalent bonds, the lone pairs are indicated, if any.  \nComparison between the properties of ionic and covalent compounds  \n\n| Ionic Covalent |  |  |\n| --- | --- | --- |\n| Description | Bond between a metal and nonmetal.
