5
Q
what does the period indicate
A
the number of energy levels
6
Q
what does the group indicate
A
the number of valence electrons
7
Q
what controls an elements chemical property
A
its valence electrons
8
Q
why do elements in the same group have similar chemical properties
A
because they have the same number of valence electrons
9
Q
what are dot diagrams
A
the symbol of the element and its valence electrons around the symbol
