Answer 1

B. Na and Li

Step-by-step explanation:

Only lithium and Sodium will have similar properties based on their groupings in the periodic table.

The periodic table of elements shows the arrangement of elements based on their atomic number.

• As general rule, elements in the same group on the periodic table will have the same chemical properties
• This is because they have the same number of valence electrons.
• Valency of an atom determines the chemical properties of such atom.
