I want to know how many atoms (the exact number) your WHOLE body has.

I learned that a human hair contains 500,000 atoms from this video:

Atoms make up elements

An Atom is the smallest unit. Atoms are Smaller than Cells

Are there nuclear reactions going on in our bodies?

# data[].attributes.body
1. There are three parts to an atom: protons, neutrons and electrons

2. Atoms make up elements. Atoms are very very tiny

3. Atoms are mainly empty space

4. There are different kinds of atoms

5. There are atoms in our bodies

6. Atoms comes from the word Uncuttable

# data[].attributes.attachment_link.readable_text
Everything in the world consists of atoms, so it's good to know something about them. Here are 10 interesting and useful atom facts.

1. There are three parts to an atom. Protons have a positive electrical charge and are found together with neutrons (no electrical charge) in the nucleus of each atom. Negatively charged electrons orbit the nucleus.

2. Atoms are the smallest particles that make up elements. Each element contains a different number of protons. For example, all hydrogen atoms have one proton while all carbon atoms have six protons. Some matter consists of one type of atom (e.g., gold), while other matter is made of atoms bonded together to form compounds (e.g., sodium chloride).

3. Atoms are mostly empty space. The nucleus of an atom is extremely dense and contains nearly all of the mass of each atom. Electrons contribute very little mass to the atom (it takes 1,836 electrons to equal the size of a proton) and orbit so far away from the nucleus that each atom is 99.9% empty space. If the atom was the size of a sports arena, the nucleus would be the size of a pea. Although the nucleus is much denser compared with the rest of the atom, it too consists mainly of empty space.​

4. There are over 100 different kinds of atoms. About 92 of them occur naturally, while the remainder are made in labs. The first new atom made by man was technetium, which has 43 protons. New atoms can be made by adding more protons to an atomic nucleus. However, these new atoms (elements) are unstable and decay into smaller atoms instantaneously. Usually, we only know a new atom was created by identifying the smaller atoms from this decay.

5. The components of an atom are held together by three forces. Protons and neutrons are held together by the strong and weak nuclear forces. Electrical attraction holds electrons and protons. While electrical repulsion repels protons away from each other, the attracting nuclear force is much stronger than electrical repulsion. The strong force that binds together protons and neutrons is 1,038 times more powerful than gravity, but it acts over a very short range, so particles need to be very close to each other to feel its effect.

6. The word "atom" comes from the Greek word for "uncuttable" or "undivided." The name comes from the 5th century BCE Greek philosopher Democritus, who believed matter consisted of particles that could not be cut into smaller particles. For a long time, people believed atoms were the fundamental "uncuttable" unit of matter. While atoms are the building blocks of elements, that can be divided into still smaller particles. Also, nuclear fission and nuclear decay can break atoms into smaller atoms.

7. Atoms are very small. The average atom is about one-tenth of a billionth of a meter across. The largest atom (cesium) is approximately nine times bigger than the smallest atom (helium).

8. Although atoms are the smallest unit of an element, they consist of even tinier particles called quarks and leptons. An electron is a lepton. Protons and neutrons consist of three quarks each.

9. The most abundant type of atom in the universe is the hydrogen atom. Nearly 74% of the atoms in the Milky Way galaxy are hydrogen atoms.

10. You have around 7 billion billion billion atoms in your body, yet you replace about 98% of them every year!

I would love to know what other kinds of atoms there are because if all atoms were the same, we would all look the same, even pets and objects! So I would love to do an experiment of where I get a close up look on atoms and see their differences.
