The Periodic Table And Bohr Model

Question 1

Three Major Groups from the periodic table

Answer 1

Metal non metal and metalloids

Question 2

Atomic Number

Answer 2

Represents the amount of protons and is located in the top left

Question 3

Atomic Mass/Mass number

Answer 3

The mass of the atom and you subtract it from the atomic number to get the amount of neutrons and don’t forget to round
