Question

Chemistry Covalent Substances?
For homework, I have to pick 3 substances that I think are covalent substances and also explain (briefly) why I think these substances are covalent. I need help finding some substances.

Answer 1

Cl2,H2,HCl. The stable balance of attractive and repulsive forces between
atoms when they share electrons is known as covalent bonding.Covalent bonds are
affected by the electronegativity of the connected atoms. Two atoms with equal
electronegativity will make nonpolar covalent bonds such as H−H (H2) or Cl-Cl
(Cl2) . An unequal relationship creates a polar covalent bond such as with H−Cl
(HCl) .
