What an Atom is Really Made Of (You Won’t Believe It!)

A atom is the the smallest particle of a chemical element that can exist. An atom can be made up of one proton, neutrons and electrons.

Protons have positive charge, electrons have negative charge and neutrons are neutral with no charge. Electrons are the least stable because they have the highest energy level.

The number of protons in an atom determines which element it belongs to because an atom’s properties are all derived from the number of protons it has in its nucleus.

1.The nucleus

Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than . 01% of the volume of the atom, but typically contains more than 99.9% of the mass of the atom.

2. The electrons

Electrons are the negatively charged particles that orbit the nucleus. They are much smaller than the other particles in the atom.

In fact, they are so small that their mass is almost negligible. Even though they are tiny, they play a big role in chemical reactions because they determine how atoms bond with each other.

3. Atoms vs. Molecules

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.

4. How it all comes together

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.

The structure of an atom is a central nucleus composed of protons and neutrons with electrons orbiting around this nucleus.
