Respuesta :
for covalent bonds , aka molecular bonds, atoms tend to share electrons equally in a chemical bond where they both are the same element.
The two atoms must have equal and opposite charges.
What is an atom?
An atom is the smallest component of an element and the building block of all matter, characterized by sharing of the chemical properties of the element and a nucleus with neutrons, protons, and electrons.
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 between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
Hence, the two atoms must have equal and opposite charges.
