What does covalent mean in science?

covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. A covalent bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.

What is ionic in science?

ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).

What is the meaning of Covalency?

US covalence / (kəʊˈveɪlənsɪ) / noun. the formation and nature of covalent bonds. the number of covalent bonds that a particular atom can make with other atoms in forming a molecule.

What is bond in science?

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

What is the best definition of a covalent compound?

Covalent Compound Definition When a molecule is formed from the covalent bond, such compounds are known as a covalent compound. These compounds share one or more pair of valence electrons. The covalent compound is a result of two non-metals reacting with each other such that they are electrically neutral.

What is the difference between molecules and ions?

Molecules are neutral particles made of two or more atoms bonded together. An ion is a positively or negatively charged particle.

What is Covalency of oxygen?

The covalency of an atom is the number of electrons it shares with other atoms when forming chemical bonds. So covalency of oxygen is two as it forms a double bond and that of nitrogen is three as it forms a triple bond.

What is the covalency of an atom?

The number of bonds an atom can form within a molecule is known as its covalency. The simplest atom, hydrogen has the capacity to form one bond; that is, it can attach itself to one other atom to form a molecule. Oxygen atoms can form two bonds and nitrogen atoms can form three within a molecule.

What is a bond simple definition?

A bond is a fixed-income instrument that represents a loan made by an investor to a borrower (typically corporate or governmental). Bonds are used by companies, municipalities, states, and sovereign governments to finance projects and operations. Owners of bonds are debtholders, or creditors, of the issuer.
