Answer to Question #84421 in Inorganic Chemistry for anuj kumar

Question

a)
Explain why all the periods in the periodic table do not have the same number of elements in them.

Answer 1

All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital. At this time, there is a maximum of seven electron orbitals.
