WebOct 18, 2024 · When the bonding is between two non-metallic atoms, a covalent bond is formed. Covalently bonded species can fall into one of two categories: elements, where all the atoms are of the same non-metal compounds, where two or more different non-metallic atoms are bonded together. WebIonic Bonds - A bond between metal and nonmetal elements. Involves transferring electrons. Covalent Bonds - Also known as molecular bonds. A bond between two nonmetals. Involves sharing electrons. Metallic Bonds - A bond exclusively between metals. It creates a bulk of metal atoms, all "clumped" together. An example of this is a … WebIn covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail. Covalent bonds … fy a-b+ 型
