18
4
32
8
2
What is the pattern observed among the elements in the same period?
Elements in a period have similar chemical characteristics
As you go from left to right, number of orbitals go up by 1
As you go from left, number of valence electrons go up by 1
3
Why do we call the table of elements a "Periodic" Table?
It shows that the elements all have different atomic masses
The properties of the elements recur when put in groups
The elements all have different properties
It shows that all the elements have different atomic numbers
4
Why are valence electrons so important?
They determine the reactivity of the element
They partially determine the atomic mass of the atom
The determine the atomic number of the atom
5
What pattern is observed among elements in the same group?
They share similar chemical characteristics
As you do down a group, number of valence electrons goes up
They have the same atomic number
