Answer to Problem 62A
Period 3, group 1, sodium form cation
Explanation of Solution
Electronic configuration of Na is
Sodium has three shells and contains 1 outermost electron. So, its position is period 3 group 1.
As only 1 electron is present in the outermost shell, it removes to gain noble gas electronic configuration, so sodium will cation.

Concept introduction:
The periodic table is a columnar structure that organizes different elements into groups based on how they behave. The elements in the periodic table of today are ordered according to the periodic law. The elements are organized in the modern periodic table in increasing order of their atomic number. When elements are arranged in increasing order of atomic number, periodic trends are observed in certain properties.

Answer to Problem 62A
Period 2, group 17, fluorine anion
Explanation of Solution
The electronic configuration of F is
Fluorine has two shells, and the outer shell contains 7 outermost electrons. So, its position is period 2 group 17.
As only 1 electron is required to gain noble gas electronic configuration, so fluorine will anion.
