1. Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.
2. A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
3. Astronomy is the study of the sun, moon, stars, planets, comets, gas, galaxies, gas, dust and other non-Earthly bodies and phenomena.
4. An Electrochemist studies the electric character of those reactions. As a Chemist who specializes in electrons, voltage, chemicals, matter, and energy, you work for universities, government agencies, and private research labs within industries as diverse as energy, medicine, and manufacturing.
Atoms => Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element.
Molecules => Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
Astronomy => Astronomy is the study of the sun, moon, stars, planets, comets, gas, galaxies, gas, dust and other non-Earthly bodies and phenomena.
Electrochemist => A science that deals with the composition, structure, and properties of substances and with the transformations that they undergo.
I hope this will help you dear..
Always stay safe and stay healthy..
