Water (H₂O) is a molecule composed of two hydrogen atoms bonded to one oxygen atom through covalent bonds. The oxygen atom shares electrons with each hydrogen atom, forming a bent molecular structure. This arrangement results in a polar molecule with oxygen carrying a partial negative charge and hydRead more
Water (H₂O) is a molecule composed of two hydrogen atoms bonded to one oxygen atom through covalent bonds. The oxygen atom shares electrons with each hydrogen atom, forming a bent molecular structure. This arrangement results in a polar molecule with oxygen carrying a partial negative charge and hydrogen atoms carrying partial positive charges.
Sugar can be considered a pure substance because it consists of a single type of molecule, either glucose or sucrose, depending on the form. However, it may contain impurities depending on its source or processing, affecting its purity.

Ions are composed of atoms or groups of atoms that have gained or lost electrons, resulting in a net positive or negative charge. This charge arises from the imbalance of protons and electrons.

In metals, atomicity typically refers to the single atoms forming metallic bonds, leading to a high degree of atomic mobility. In non-metals, atomicity often refers to molecules composed of two or more atoms bound by covalent bonds, exhibiting limited atomic mobility.
