(a)
Interpretation:
The period and group number of element oxygen are to be determined.
Concept Introduction:
The periodic table is used to arrange the elements on the basis of their characteristics. In the periodic table, row is called a period and column is called a group. There is a total of 18 groups and 7 periods in the periodic table.
(b)
Interpretation:
The period and group number of element calcium are to be determined.
Concept Introduction:
The periodic table is used to arrange the elements on the basis of their characteristics. In the periodic table, row is called a period and column is called a group. There is a total of 18 groups and 7 periods in the periodic table.
