mn and si are ________and ______, respectively.

1. alkaline earth metal and nonmetal
2. transition metal and halogen
3. transition metal and semimetal
4. nonmetal and semimetal

Explanation:

To solve this, we analyze the elements: Mn (Manganese) is a transition metal (found in the d - block of the periodic table). Si (Silicon) is a semimetal (has properties of both metals and non - metals). Now we check the options:

• Option 1: Alkaline earth metals are in group 2, Mn is not an alkaline earth metal. Eliminate.
• Option 2: Halogens are in group 17, Si is not a halogen. Eliminate.
• Option 3: Mn is a transition metal and Si is a semimetal. This matches.
• Option 4: Mn is a metal (transition metal), not a non - metal. Eliminate.

Answer:

1. Transition metal and semimetal
