What does the atomic weight (mass number) of an element represent?
36
the atomic size will decrease as you move across the period
Number of Neutrons = Mass Number - Atomic Number
100
how much the atom weighs
83.80
The atomic size will increase as you move across the period
groups
As you move from left to right across the periodic table:
36
the atomic size will decrease as you move across the period
Number of Neutrons = Mass Number - Atomic Number
100
how much the atom weighs
83.80
The atomic size will increase as you move across the period
