Aneutral atom has 2 electrons in the first energy level and 3 electrons in the second energy level. which atom is this?

helium

boron

beryllium

carbon

The answer to your question is: Boron

Explanation:

Helium  has 2 electrons in the first energy level and does not have any electron in the second energy level.

Boron  it has 2 electrons in the first energy level and three electrons in the second energy level.

Beryllium  has 2 electrons in the first energy level and 2 electrons in the seond energy level.

Carbon has 2 electrons in the first energy level and 4 electrons in the third energy level.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
