Concept explainers
(a)
To determine: A list of the elements in the first two rows of the periodic table with their numbers of valence electrons.
Interpretation: A list of the elements in the first two rows of the periodic table with their numbers of valence electrons is to be shown.
Concept introduction: Periodic table is a systematic arrangement of all the elements present in nature. The periodic table which is used in the present time is called modern periodic table. It is based on periods and groups. The horizontal rows are called periods and vertical columns are called groups.
(b)
To determine: The use of the list to construct first two rows of the periodic table.
Interpretation: The use of the list to construct first two rows of the periodic table is to be stated.

(c)
To add: The elements sulfur, phosphorus, chlorine, bromine, and iodine in the periodic table representation.
Interpretation: The elements sulfur, phosphorus, chlorine, bromine, and iodine are to be represented in the periodic table.
