Answer to Problem 2.20QP

Solution

The number of neutrons, number of protons and number of electrons for the given atom are 6_ , 5_ and 5_ , respectively.

Explanation of Solution

Explanation

The atomic number of 11B is 5 and atomic mass is 11 .

Calculate the number of neutrons by formula,

Numberofneutrons=atomicmassatomicnumber

Substitute value of atomic number and atomic mass in above formula,

NumberofNeutrons=115=6

Therefore, the number of neutrons are 6_ .

The number of proton is equal to the atomic number of element. Therefore, the number of protons in 11B are 5_ .

The number of electrons is equal to atomic number or number of protons. Therefore, the number of electrons in 11B are 5_ .

Answer to Problem 2.20QP

Solution

The number of neutrons, number of protons and number of electrons for the given atom are 10_ , 9_ and 9_ , respectively.

Explanation of Solution

Explanation

The atomic number of 19F is 9 and atomic mass is 19 .

Calculate the number of neutrons by formula,

Numberofneutrons=atomicmassatomicnumber

Substitute value of atomic number and atomic mass in above formula,

NumberofNeutrons=199=10

Therefore, the number of neutrons are 10_ .

The number of proton is equal to the atomic number of element. Therefore, the number of protons in 19F are 9_ .

The number of electrons is equal to atomic number or number of protons. Therefore, the number of electrons in 19F are 9_ .

Answer to Problem 2.20QP

Solution

The number of neutrons, number of protons and number of electrons for the given atom are 78_ , 53_ and 53_ , respectively.

Explanation of Solution

Explanation

The atomic number of 131I is 53 and atomic mass is 131 .

Calculate the number of neutrons by formula,

Numberofneutrons=atomicmassatomicnumber

Substitute value of atomic number and atomic mass in above formula,

NumberofNeutrons=13153=78

Therefore, the number of neutrons are 78_ .

The number of proton is equal to the atomic number of element. Therefore, the number of protons in 131I are 53_ .

The number of electrons is equal to atomic number or number of protons. Therefore, the number of electrons in 131I are 53_ .

Answer to Problem 2.20QP

Solution

The number of neutrons, number of protons and number of electrons for the given atom are 136_ , 86_ and 86_ , respectively.

Explanation of Solution

Explanation

The atomic number of 222Rn is 86 and atomic mass is 222 .

Calculate the number of neutrons by formula,

Numberofneutrons=atomicmassatomicnumber

Substitute value of atomic number and atomic mass in above formula,

NumberofNeutrons=22286=136

Therefore, the number of neutron is 136_ .

The number of proton is equal to the atomic number of element. Therefore, the number of protons in 222Rn are 86_ .

The number of electrons is equal to atomic number or number of protons. Therefore, the number of electrons in 222Rn are 86_ .

Conclusion

  1. a. The number of neutrons, number of protons and number of electrons for the given atom are 6_ , 5_ and 5_ , respectively.
  2. b. The number of neutrons, number of protons and number of electrons for the given atom are 10_ , 9_ and 9_ , respectively.
  3. c. The number of neutrons, number of protons and number of electrons for the given atom are 78_ , 53_ and 53_ , respectively.
  4. d. The number of neutrons, number of protons and number of electrons for the given atom are 136_ , 86_ and 86_ , respectively
