What are the three particles of an atom?
Changing the number of electrons
What is making an ion?
An element with different number of neutrons than the periodic table
The name of the rows that go across
What are Periods?
The electrons on the outer shell
What is valence electrons
Particle of an atom with a positive charge, located in the nucleus.

The number below the symbol of the element
What is the atomic number?
The name of the columns that go down
What are Groups?
Where the electrons live in different levels
What are Energy shells?
electrons orbit around the nucleus in
What is electron shell or electron cloud?
The number to the top left of the symbol of the element
