Give electron configurations for atoms of these elements: na, s, mg, ne, and k.

Answer :

The electronic configuration of sodium atom is,

The electronic configuration of sulfur atom is,

The electronic configuration of sulfur atom is,

The electronic configuration of sulfur atom is,

The electronic configuration of sulfur atom is,

Explanation :

Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.  

Number of electrons in an atom are determined by the electronic configuration.

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

(a) The given atom is, sodium (Na)

Atomic number of Na = 11

Number of electrons = 11

The electronic configuration of sodium atom is,

(b) The given atom is, sulfur (S)

Atomic number of S = 16

Number of electrons = 16

The electronic configuration of sulfur atom is,

(c) The given atom is, magnesium (Mg)

Atomic number of Mg = 12

Number of electrons = 12

The electronic configuration of sulfur atom is,

(d) The given atom is, neon (Ne)

Atomic number of Ne = 10

Number of electrons = 10

The electronic configuration of sulfur atom is,

(e) The given atom is, potassium (K)

Atomic number of K = 19

Number of electrons = 19

The electronic configuration of sulfur atom is,

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.
