Give the number of protons, electrons, and neutrons in neutral atoms of each of the following isotopes:
(a) 7,3 li
(b) 125,52 te
(c) 109,47 ag
(d) 15,7 n
(e) 31,15 p

(a) 7,3 Li: 3 protons, 3 electrons, 4 neutrons.

(b) 125,52 Te: 52 protons, 52 electrons, 73 neutrons.

(c) 109,47 Ag: 47 protons, 47 electrons, 62 neutrons.

(d) 15,7 N: 7 protons, 7 electrons, 8 neutrons.

(e) 31,15 P: 15 protons, 15 electrons, 16 neutrons.

Explanation:

In the case of the isotopes in neutral atoms, the number of electrons and protons is equal to the atomic number, the number of neutrons is equal to the number of the isotope minus the atomic number.

(a) 7,3 Li

The number of protons: 3.

Number of electrons: 3.

Number of neutrons: 7-3=4.

(b) 125,52 Te

The number of protons: 52.

Number of electrons: 52.

Number of neutrons: 125-52=73.

(c) 109,47 Ag

The number of protons: 47.

Number of electrons: 47.

Number of neutrons: 109-47=62.

(d) 15,7 N

The number of protons: 7.

Number of electrons: 7.

Number of neutrons: 15-7=8.

(e) 31,15 P

The number of protons: 15.

Number of electrons: 15.

Number of neutrons: 31-15=16.

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.
