Question

35Cl and 37Cl are two isotopes of chlorine.

a. What is the numbers of protons, neutrons, and electrons in 35Cl if the atom is electrically neutral?

b. What is the numbers of protons, neutrons, and electrons in 37Cl if the atom is electrically neutral?

c. What is the numbers of protons, neutrons, and electrons in 35Cl if the ion has a -1 charge?

d. What is the numbers of protons, neutrons, and electrons in 37Cl if the ion has a -1 charge?

e. What is the numbers of protons, neutrons, and electrons in 35Cl if the ion has a 4 charge?

f. What is the numbers of protons, neutrons, and electrons in 37Cl if the ion has a 4 charge?

Explanation / Answer

Atomic number of chlorine is A = 17.

a)

Number of proton = 17

Number of electron = 17

NUmber of neutrons N = M- A = 35-17 = 18

b)

Number of proton = 17

Number of electron = 17

NUmber of neutrons N = M- A = 37-17 = 20

c) -1 electrically charge is like one electron extra

Number of proton = 17

Number of electron = 18

NUmber of neutrons N = M- A = 35-17 = 18

d) -1 charge is like adding on electron

Number of proton = 17

Number of electron = 18

NUmber of neutrons N = M- A = 37-17 = 20

e) 4 charge is like removing 4 electrons

Number of proton = 17

Number of electron = 13

NUmber of neutrons N = M- A = 35-17 = 18

f) 4 charge is like removing 4 electrons

Number of proton = 17

Number of electron = 13

NUmber of neutrons N = M- A = 37-17 = 20
