A chemical bond formed between two ions with opposite charges. Viruses possess both living and non-living characteristics. Similarities between Covalent Bond and Ionic Bond. In this case, this is called electrostatic repulsion. Conversely, an ionic compound that has hydroxide (OH–) or oxide (O2-) is classified as a base. This video is unavailable. One of the resulting ions carries a negative charge (anion), and the other ion carries a positive charge (cation). Chemical bonds, such as ionic bonds, help form a chemical compound. Chem. 1 Ionic bond. Similar to the ionic bond, the hydrogen bond entails an electrostatic force. The strength of this attraction depends on the size of the atom’s charge, the distance between two atoms, and other forces acting on the atoms. Taking the square of the bond ionicity, i μ 2 (i,j), for molecular orbital μ in the localized orbital representation of Cisolowski and Mixon (J. As the name implies, a hydrogen bond is a chemical bond wherein hydrogen serves as a bridge between two atoms. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. Ø Both covalent and ionic bonds are strong bonds. Figure 1. An ionic bond is actually the extreme case of a polar covalent bond, the latter resulting from unequal sharing of electrons rather than complete electron transfer. Hydrogen bond forms when the slightly positive hydrogen atom of a polar covalent bond forms an electrostatic link with the more electronegative atom of a polar covalent bond in the same or another molecule. For an ionic bonding to occur there must be an electron donor (often a metal) and an electron acceptor (often a nonmetal). This is as opposed to the phenomenon wherein ions or atoms with the same charge tend to repel. Ionic bonds are formed due to the attraction between an atom that has lost one or more electron and an atom that has gained one or more electrons. Ionic bond. Ionic Bond Definition . Covalent Bonds vs Ionic Bonds. The atom that loses one or more electrons will turn into a positive ion and will be called a cation. Ionic bonds require more energy to break in comparison to covalent bonds.
