Question

1. How are covalent bonds formed ?
​

Answer 1

Answer:

by sharing electrons

Explanation:

Shared electrons located in the space between the two nuclei are called bonding electrons

Answer 2

Answer:

consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. 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 “glue” that holds the atoms together in molecular units.a

Explanation:

ex- H•+ H• -> H - H
