Question

How do atoms usually exist in nature?

Answer 1

Hint: The smallest unit of ordinary matter that makes up a chemical element is an atom. Atoms that are neutral or ionised make up any solid, liquid, gas, and plasma. Atoms are incredibly thin, measuring about $100$ picometers in diameter. Every atom is made up of a nucleus and one or more electrons attached to it.

Complete answer:
Many elements' atoms exist in the form of a molecule or an ion since they are the most reactive. Hydrogen, oxygen, chlorine, and other elements are examples. In nature, however, non-reactive atoms of certain elements occur in a free-state. Helium, neon, argon, and other noble gases are examples.
Atoms are typically found in one of two states:
In molecular form
In ionic form
In general, a molecule is a set of two or more atoms that are chemically bound, or held together by attractive forces. A molecule is the smallest particle of an element or compound capable of independent life and displaying all of the substance's properties. Atoms from the same or different elements may combine to form a molecule.
Charged species can be found in metal and nonmetal compounds. Ions are charge-carrying animals. Ions are charged particles that can be either positively or negatively charged. An anion is a negatively charged ion, and a cation is a positively charged ion. Take sodium chloride, for example ($NaCl$). Positively charged sodium ions ($N{a}^{+}$) and negatively charged chloride ions ($C{l}^{-}$) make up the constituent particles. Ions may be made up of a single charged atom or a set of atoms with a net charge. A polyatomic ion is a group of atoms that have a charge.

Note:
The electromagnetic force attracts an atom's electrons to its protons in the atomic nucleus. The nuclear force attracts protons and neutrons in the nucleus to each other.
