All of the elements in a period have the same number of atomic orbitals.
Explanation:
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.
Elements in the same period all have the same number of valence electrons.
Explanation:
"Elements present in horizontal rows are called as periods so elements belonging to the same period have same number of shell as the electrons are added in the same shell of the element."
