Top 10 unbelievable historical concurrencies. A glucocorticoid is a type of steroid hormone which is produced in the cortex of the adrenal gland: cortisol is probably the most well known and common example of a glucocorticoid.
carbon is a special eleme having 4 electron in its outer shell so to complete its octect it needs to share its electron in a covalent bond. carbon is a special eleme having 4 electron in its outer shell so to complete its octect it needs to share its electron in a covalent bond.
Many elements are not chemically stable by themselves; by sharing electrons, an atom gains stability. In a chemical formula, the octet rule strongly governs the number of atoms for each element in a molecule; for example, calcium fluoride is CaF2 because two fluorine atoms and one calcium satisfy the rule.or the carbon dioxide molecule, for example, one carbon atom bonds with two oxygen atoms. Carbon, with four electrons in its valence shell, needs four to reach the octet state. Oxygen, with six outer electrons, needs two.
