An atom is a particle of matter that characterizes a chemical element. It is the smallest part of ordinary matter. It is made from particles called protons, neutrons and electrons called the subatomic particles.
☆》》elements▪▪▪
An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.
☆》》molecules ▪▪▪
Molecules, in general, are the smallest entities that can represent the chemical properties of a compound.
Molecules are formed when two or more atoms react and chemically combine under certain conditions. Molecules can be categorized as homonuclear and hetero nuclear.
☆》》compounds ▪▪▪
A compound is a substance that is made up of two or more different elements that are chemically joined, such as H2o,Nacl,Co
ELEMENTS▶. An element is a substance which can't be split up into two or more simpler substance by applying heat light and electric energy.
MOLECULES▶ A molecule is a smallest unit into which a substance can be divided without changing its chemical nature.
COMPOUNDS▶ A compound is a substance which is made up of two or more elements chemically combined in a fixed proportion.
ATOMS▶ Atom is the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons.
