Notes p. 4 - Atoms

  • Atoms are the building blocks of matter. They make up everything around us.

​

  • It is sort of how bricks are the building blocks of houses.

There are three parts of an atom

​

  • Proton = positive

​

  • Neutron = neutral

no charge

​

  • Electron = negative

​

5 of 35

Protons

  • Are located in the inside of the nucleus

​

  • They have a positive charge

​

6 of 35

Neutrons

  • Are located in the inside of the nucleus

​

  • They have a neutral charge

​

7 of 35

Electrons

  • Are located outside of the nucleus in shells

​

  • They have a negative charge

​

  • They are much smaller than protons and neutrons

Nucleus

  • The nucleus is made of protons and neutrons

​

  • The amount of protons is equal to the electrons.

This means atoms are neutral and do not have a charge!

Don’t remember your atom?

Count your number of protons and then find the correct element on the periodic table up front.

Example:

​

7 protons = atomic # 7
