What would a Bohr model of Sodium (Na) look like?
APE= 11, Mass= 22.99(23), N= 12
300
How can you determine how many energy levels an element has?
Find what period it is on and/or calculate the number of electrons in the atom.
300
What is a period and how many are located on the periodic table?
Horizontal rows on the periodic table indicated by the numbers on the left or right of the chart. Each period has the same energy levels. There are 7 periods total.
300
How do you determine the reactivity of an element?
Elements on the periodic table become more reactive as you move out from the center (groups 3-12).
400
If you do not know what the mass of an element is, but you do have the atomic number and neutrons, how can you determine the atomic number?
Atomic number + neutrons = Mass
400

What does APE MAN stand for and how does it help you to locate elements?
APE: atomic number = protons = electrons
Man: mass - atomic number = neutrons
Its used to find the atomic number and mass to identify its location.
