a covalent chemical bond is one in which

Best answer


A covalent bond in chemistry is a chemical link between two atoms or ions in which theelectron pairs are shared between them. A covalent bond may also be termed a molecular bond. Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values.

  • What is a covalent bond?

  • A covalent bond is a chemical link between two atoms or ions where the electron pairs are shared between them. A covalent bond may also be termed a molecular bond. … Covalent bonds form between two nonmetal atoms with identical or relatively close electronegativity values.

  • How many covalent bonds can an atom form?

  • The hydrogen atom and the halogen atoms form only one covalent bond to other atoms in stable neutral compounds. However, the carbon, oxygen, and nitrogen atoms can bond to more than one atom. The number of covalent bonds an atom can form is called the valence of the atom.

  • Which type of covalent bond is formed when two atoms combine?

  • This type of covalent bond is formed whenever there is an equal share of electrons between atoms. The electronegativity difference between two atoms is zero. It occurs wherever the combining atoms have similar electron affinity (diatomic elements). Example, Nonpolar Covalent Bond is found in gas molecules like Hydrogen gas, Nitrogen gas, etc.

  • What holds atoms together in a covalent bond?

  • A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the 鈥済lue鈥?that holds the atoms together in molecular units.
