What is a pure

substance?

Is a substance in which there is a uniform composition

of “particles”. Theparticles we aretalking about are atoms.

What is a compound?

Is a combination of elements that come together through a chemical reaction and becomes something called a molecule. A molecule is two or

more different elements combined in a specific ratio.

What is the

atomicnumber?

The atomic number is the number ofProtons in the nucleus of that atom. All atoms ofan element have the same atomic number.

Here is an example of one of the elements on the periodic table.

Starting Simply The hydrogen atom has one proton and one electron.

Now for Some Neutrons The helium atom has two protons, two neutrons, and two electrons.

Building Bigger Atoms For bigger atoms, simply add protons, neutrons, and electrons.

Protons and Atomic Number . The atomic number represents the number of protons in the nucleus of the atom.
