Chapter 2: Q2TYU (page 28)

Compared with 31P, the radioactive isotope 32P has

(A) a different atomic number.

(B) one more proton.

(C) one more electron.

(D) one more neutron.

Short Answer

Expert verified

(A) The statement 鈥渁 different atomic number鈥� is false.

(B) The statement 鈥渙ne more proton鈥� is false.

(C) The statement 鈥渙ne more electron鈥� is false.

(D) The statement 鈥渙ne more neutron鈥� is true.

Step by step solution

01

Explanation of option ‘(A)’

The atoms consist of three different subatomic particles such as protons, neutrons, and electrons. The atomic number corresponds to a number of protons.

The radioisotopes such as31P and 32P do not differ in the number of protons, so the atomic number difference is not seen in these two radioisotopes.

Thus, the atomic number is not the influencing factor in the radioisotopes.

Therefore, the given statement is false.

02

Explanation of option ‘(B)’

Protons are the positively charged particles present in the nucleus of the atom. Radioisotopes are elements that are not related to the numberof protons. The difference in 31P and 32P is not due to the presence of one more proton.

Thus, radioactive isotopes are elements that are unrelatedto protons.

Therefore, the given statement is false.

03

Explanation of option ‘(C)’

Electrons are negatively charged particles that revolve around the nucleus of the atom. These electrons are not the difference between two radioisotopes. The difference in 31P and 32P is not due to the presence of one more electron.

Thus, electrons are negatively charged particles that are not responsible for the difference between the radioisotopes.

Therefore, the given statement is false.

04

Explanation of option ‘(D)’

Radioisotopes are the elements that possess the radioactive property. Mainly radioisotopes are used for nuclear fission and fusion reactions because they can liberate large amounts of energy in the form of radiation.

The radioisotopes differ in the neutron number from the other radioisotopes. The neutron number is the number of neutral molecules present with the atom.

The difference in 31P and 32P is due to the presence of one more neutron.

Therefore, the given statement is true.

Most popular questions from this chapter

A standard curve of radioactive isotope decay is shown at the top of the right column. The graph line shows the fraction of the radioactive isotope over time (before present) in units of half lives. Recall that a half-life is the amount of time it takes for half of the radioactive isotope to decay. Labeling each data point with the corresponding fractions will help orient you to this graph. Draw an arrow to the data point for half-life = 1 and write the fraction of 14C that will remain after one half life. Calculate the fraction of 14C remaining at each half-life and write the fractions on the graph near arrows pointing to the data points. Convert each fraction to a decimal number and round off to a maximum of three significant digits (zero at the beginning of the number do not count as significant digits). Also write each decimal number in scientific notation.

In Figure 2.7, if two or more elements are in the same row, what do they have in common? If two or more elements are in the same column, what do they have in common?

How many electrons does fluorine have? How many electron shells? Name the orbital that is occupied. How many electrons are needed to fill the valence shell?

The percentage of naturally occurring elements making up the human body (see table2.1) is similar to the percentage of these elements found in other organisms. How could you account for this similarity among organisms?

A nitrogen atom has 7 protons, and the most common isotope of nitrogen has 7 neutrons. A radioactive isotope of nitrogen has 8 neutrons. Write the atomic number and mass number of this radioactive nitrogen as a chemical symbol with a subscript and superscript.
