what is covalent bond? give two example
Answers
Answer:
Covalent bonding occurs between non-metal elements when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms to attain the nearest noble gas electron configuration. Here when elements share their electrons, they do not become positive or negative, since they are neither gaining nor sacrificing electrons. Thus no ions are formed by covalent bonding. Based on the number of shared electron pairs, there are three types of covalent bond. Namely, single covalent bond, double covalent bond and triple covalent bond.
Examples of Covalent Bonding. Methane molecule (CH4) The electronic configuration of carbon is 2,4. It needs 4 more electrons in its outer shell to be like the noble gas neon.Water molecule (H2O) One oxygen atom joins with two hydrogen atoms.Carbon dioxide (CO2) One carbon atom joins with two oxygen atoms.
