Answer:

In chemistry, atom is the smallest particle of an element

Explanation:

Atoms are smallest particle of an element.

For example, when you have a substance, lets say an apply, and you keep on cutting it, It will reach a point in which you will be unable to cut it anymore, at that point we call the particle an atom.

Atoms are neutral in charge. Inside the atoms, there is a nucleus which consist of proton, neutron and electrons. The protons  are positively charged,  the electrons are negatively charged. There are equal number of protons and electrons in an atom, this make the atom to be neutral in charges.

Atoms are the building block of any materials or substance.
