How do atoms in molecules bond? <br> plz answer I will give brainliest
spin [16.1K]

Answer:

Via covalent bonds

Explanation:

Atoms in molecules are bonded together via covalent bonds. Covalent bonds are bonds that are formed by sharing of the valence electrons between two atoms.

The atoms can be of the same kind or of different kinds.

  • In most molecules, the two atoms are connected by sharing of their valence electrons.
  • This way, each atom can attain stability by becoming isoelectric with the nearest noble gas.
  • Some molecules are monoatomic, some are polyatomic.
