exemples of elements with 1 valence electron: Hydrogen, lithium, potassium.

exemples of elements with 2 valence electrons: magnessium, calcium.

boron has 3 valence electrons. Phosphorus has 5 valence electrons.

carbon has 4 valence electrons.

exemples of elements with 5 valence electrons: Phosphorus, nitrogen

exemples of elements with 7 valence electrons: fluorine, chlorine

exemples of elements with 8 valence electrons: helium, argon

Explanation:

the easiest way to know the number of electrons are by the number of the group so 14 is 4, 16 is 6.

answer: $2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

the reaction is type of combination reaction.

explanation:

$? c_5h_5+? fe\rightarrow ? fe(c_5h_5)_2$

on the product side, there are 2 molecules of $c_5h_5$ bonded to fe   which means one atom of fe are combined two molecules of $c_5h_5$. so, balanced chemical equation becomes :

$2c_5h_5+1fe\rightarrow 1fe(c_5h_5)_2$

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.

$a+b\rightarrow ab$
