Structure Of Periodic Table

Question 1

Pattern of the reactivity of metals

Answer 1

Increases as you go down a group
Decreases as you go along a period

Question 2

Pattern of reactivity in non metals

Answer 2

Group 8 elements are the most unreactive
Decreases as you go down a group
Increases as you go along a period

Question 3

Electron trends down a group

Answer 3

-the number of outer shell electrons is the same
-the number of complete electron shells increases by one.
-The number of a group is the same as the number of electrons in the
outer shell of elements in that group, except for group 0.

Question 4

Electron trends along a period

Answer 4

-the number of outer shell electrons increases by one
-the number of complete electron shells stays the same.
-The point at which a new period starts is the point at which electrons begin to fill a new shell.
