Interpretation Introduction

(a)

Interpretation:

Then appropriate symbol for the given particles using the ZAX symbolism is to be stated.

Concept introduction:

The atomic number of an element determines the number of protons and the number of electrons in a neutral atom. The mass number is the sum of a number of protons and the number of neutrons. An element is represented using the symbol ZAX where A is the mass number and Z is the atomic number of the element X.

Answer to Problem 10.7E

The symbol of tin-117 nucleus is 50117Sn.

Explanation of Solution

The given element is tin. The symbol of tin is Sn. The atomic number of tin is 50. The given mass number of tin is 117. An element can be represented using the symbol ZAX where A is the mass number and Z is the atomic number of the element X. Therefore, the symbol of tin-117 nucleus is 50117Sn.

Conclusion

The symbol of tin-117 nucleus is 50117Sn.

Interpretation:

Then appropriate symbol for the given particles using the ZAX symbolism is to be stated.

Concept introduction:

The atomic number of an element determines the number of protons and the number of electrons in a neutral atom. The mass number is the sum of a number of protons and the number of neutrons. An element is represented using the symbol ZAX where A is the mass number and Z is the atomic number of the element X.

Answer to Problem 10.7E

The symbol of chromium (Cr) isotope containing 26 neutrons is 2450Cr.

Explanation of Solution

The given element is chromium. The symbol of chromium is Cr. The atomic number of chromium is 24 which is equal to the number of protons. The given number of neutrons in chromium is 26. The mass number of an element can be calculated as follows.

Massnumber=Numberofprotons+Numberofneutrons

Substitute the values of a number of protons and that of neutrons in the above equation.

Massnumber=Numberofprotons+Numberofneutrons=24+26=50

Therefore, the value of the mass number of chromium is 50.

An element can be represented using the symbol ZAX where A is the mass number and Z is the atomic number of the element X. Therefore, the symbol of chromium (Cr) isotope containing 26 neutrons is 2450Cr.

Conclusion

The symbol of chromium (Cr) isotope containing 26 neutrons is 2450Cr.

An element is represented using the symbol ZAX where A is the mass number and Z is the atomic number of the element X.

Answer to Problem 10.7E

The symbol of the nucleus of the element number 20 that contains 24 neutrons is 2044Ca.

Explanation of Solution

The atomic number of a given element is 20, therefore, the given element is calcium. The symbol of calcium is Ca. The number of protons is equal to the atomic number. The given number of neutrons in calcium is 24. The mass number of an element can be calculated as follows.

Massnumber=Numberofprotons+Numberofneutrons

Substitute the values of a number of protons and that of neutrons in the above equation.

Massnumber=Numberofprotons+Numberofneutrons=20+24=44

Therefore, the value of the mass number of calcium is 44.

An element can be represented using the symbol ZAX where A is the mass number and Z is the atomic number of the element X. Therefore, the symbol of the nucleus of an element number 20 that contains 24 neutrons (calcium) is 2044Ca.

Conclusion

The symbol of the nucleus of the element number 20 that contains 24 neutrons is 2044Ca.
