Detailed explanation-1: -Molecules are made up of one or more atoms connected by covalent (chemical) bonds.
Detailed explanation-2: -When two atoms bond together, they form molecules. Thus, molecules are a group of atoms that have been held together by chemical bonds. These bonds can either be covalent, ionic bonds, or intramolecular forces. Atoms form molecules by sharing electrons, e.g., in the formation of simple molecules such as oxygen.
Detailed explanation-3: -Answer: Molecules are made up of two or more atoms.
Detailed explanation-4: -A molecule is two or more atoms connected by chemical bonds, which form the smallest unit of a substance that retains the composition and properties of that substance. Molecules form the basis of chemistry.
Detailed explanation-5: -A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. The shared electrons are attracted to the nuclei of both atoms. This forms a molecule consisting of two or more atoms.
