(a)
Interpretation:
The number of valence electrons in elements of Group
Concept introduction:
The periodic table represents elements in order of their increasing
(b)
Interpretation:
The number of valence electrons in elements of Group
Concept introduction:
The periodic table represents elements in order of their increasing atomic numbers. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are seven periods and eighteenth groups in the modern periodic table.
(c)
