The periods and groups on the periodic table are numbered.
For example, the element neon (Ne) is in period 2, group 18. Neon is
an inert gas and therefore does not react readily with any other ele-
ment. Which of the following elements is likely to have properties that
are similar to those of neon?
A. Lithium(Li) in period 2, group1
B. Boron(b) in period 2, group 13
C. Iron(Fe) in period 4, group 13
D. Krypton(Kr) in period 4, group 18
