Question

elements present in the same same period of periodic table have same:
A- Shielding Effect
B- Chemical Properties
C- Physical Properties
D- Number of Valence Electrons​

Answer 1

Answer:

● Elements present in the same period of periodic table have same Number of Valence Electrons.

Answer 2

Answer:

Elements present in the same period of the periodic table have the same number of valence electrons.

Explanation:

• All the elements in the same period have the same number of atomic shells.
• Therefore, they have the same number of valence electrons as well.
• For instance, elements in the second period have two orbitals for the electrons to move in.
• Similarly, the elements in the third period have three orbitals for the electrons to move in.
• As we go down, the number of orbitals increases.
• Each period has specific characteristics.
• For example, magnesium and sodium share similar qualities as they appear in the same row.
