What Is An Atom?

An atom is the basic unit that everything is made of. Like you need letters to make a word, you need atoms to make anything.

Atoms are very tiny. The largest one would be about 200,000 times smaller than the width of your hair, in simple language we can say that atoms are invisible. To see them , you need special tools and instruments.

So far scientists know about 118 different kinds of atoms. These kinds of atoms are called elements.

The Structure of Atoms!

...

The basic particles that make up an atom are electrons, protons, and neutrons. There are different kinds of atoms based on the number of electrons, protons, and neutrons each atom contains.

At the centre of the atom is the nucleus. The nucleus is made up of the protons and neutrons. The electrons spin in orbits outside of the nucleus.

The proton is a positively charged particle that is located at the centre of the atom in the nucleus whereas an electron is a negatively charged particle that spins around the outside of the nucleus.

The neutron doesn't have any charge.

In this basic chemistry video for kids, an atom takes the shape of a human face and explains everything about itself in a very funny way – its structure, its particles, how protons and neutrons move.
