Question

Write the atomic symbol (A/Z X) for each of the following isotopes.

a. Z=8, number of neutrons=9
b. the isotope of chlorine in which A=37
c. Z=27, A=60
d. number of protons =26. number of neutrons=31
e. the isotope of I wish a mass number of 131
f. z=3, number of neutrons=4

Answer 1

The atomic symbols for the isotopes provided are ^{17}O, ^{37}Cl, ^{60}Co, ^{57}Fe, ^{131}I, and ^{7}Li, based on the given combinations of atomic numbers, mass numbers, and numbers of neutrons.

Step-by-step explanation:

The question deals with writing the atomic symbol for different isotopes, by providing either the atomic number (Z), mass number (A), or the number of protons and neutrons. Here are the atomic symbols for the isotopes mentioned:

a. The isotope with Z=8 (oxygen) and number of neutrons=9 is ^{17}O (A=Z+N, A=8+9=17).

b. The isotope of chlorine with A=37 is ^{37}Cl (Z=17 for chlorine).

c. For Z=27 (cobalt), A=60, the atomic symbol is ^{60}Co.

d. With number of protons=26 (iron) and number of neutrons=31, the isotope is ^{57}Fe (A=26+31=57).

e. The isotope of iodine (I) with a mass number of 131 is ^{131}I (Z=53).

f. For z=3 (lithium), number of neutrons=4 the atomic symbol is ^{7}Li (A=3+4=7).
