Question

Which element does Lithium (Li) share more properties with, Beryllium (Be) or Sodium (Na)?Lithium has more common properties with Beryllium than Sodium, because they have the same number of electron shells.

Lithium has more common properties with Sodium than Beryllium, because they have the same number of valence electrons.

Answer 2

Answer: The correct answer is lithium has more common properties with Sodium than Beryllium, because they have the same number of valence electrons.

Step-by-step explanation:

Lithium is the 3rd element of the periodic table having electronic configuration
`1s^22s^1`. This element belongs to Group 1 of the periodic table.

Elements that belong to same group show similar chemical properties because they have same number of valence electrons.

Beryllium is the 4th element of the periodic table that belongs to group 2 of the periodic table.

Sodium is the 11th element of the periodic table that belongs to group 1 of the periodic table.

As, sodium and lithium belongs to same group and have same number of valence electrons.

Hence, the correct answer is lithium has more common properties with Sodium than Beryllium, because they have the same number of valence electrons.
