GEOLOGY

Detailed explanation-1: -Particles can be atoms, molecules or ions. Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together. An ion is a positively or negatively charged particle.

Detailed explanation-2: -Molecules are the collections of atoms, that is Water is composed of Oxygen and Hydrogen atoms, Proteins are made of Carbon, Hydrogen, Oxygen, and different components. Therefore, the molecules that make up the cells of the body are made of atoms.

Detailed explanation-3: -The simplest, smallest unit of matter is the atom. Atoms bond together to form molecules, and molecules come together to form cells, the smallest unit of life.

Detailed explanation-4: -Molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom).

Detailed explanation-5: -Atoms are even smaller than molecules. Molecules are made up of atoms. Dust, air, water, people-everything is made of atoms.
