WebOct 3, 2024 · (i) Monoatomic molecules: Noble gases like helium, neon, etc., exist as single atom. Hence, their molecules are monoatomic. (ii) Diatomic molecules: For example, in a molecule of hydrogen, two atoms of … WebMolecules result from the covalent bonding of two or more elements’ atoms. Covalent bonds are strong bonds in which electrons circling the atomic nucleus are shared. The nature of the covalent bond is determined by the number of electrons shared and the nature of the two elements sharing the bond.

Facts that Matter • Law of Chemical Combination Given by Lavoisier and Joseph L. Proust as follows: (i) Law of conservation of mass: Mass can neither be created nor destroyed in a chemical reaction. WebAtoms chemically bond together to form molecules, and the composition of a molecule is given by its chemical formula (O 2, H 2 O, C 6 H 12 O 6 ). When the atoms in a molecule are different, the molecule is a compound (H 2 O and C 6 H 12 O 6, but not O 2 ).
WebMolecules can be simple, consisting of only a few atoms or complex containing thousands of atoms. For example, the simple molecule oxygen is a gas found in the air we breathe. It consists of two oxygen molecules chemically bonded together (O 2). By contrast, the carbon atoms in a 1-carat diamond weighing 0.2g contain 1022 atoms.
