Problem 94

The element oxygen has three naturally occurring isotopes, with 8, 9, and 10 neutrons in the nucleus, respectively, (a) Write the full chemical symbols for these three isotopes, (b) Describe the similarities and differences between the three kinds of atoms of oxygen.

Step-by-Step Solution:

Solution : Step 1 : Isotopes are atoms with the same number of p rotons but have different number of neutrons. Since the atomic number is equal to the number ofp rotons and the mass number is the sum of protons and eutrons, isotopes can be defined as element with the same a tomic number but different mass numbers. The chemical symbol of an isotope containssuperscript an d ubscript. The superscript represents the mass number and the subscript represents the atomic number. (a) Write the full chemical symbols for these three isotopes : Oxygen is a element having chemical symbol O and atomic number 8. Atomic number indicates nu mber of p rotons and lectrons as nu mber of rotons and lectrons are equal in neutral state. Mass number is the sum of number of protons and neutrons. Here we are given the nu mber of neutrons and from atomic number we knownumber of p rotons, using this data we could predict the isotopes of oxygen having 8,9 and 10 neutrons with chemical symbol as : (i) - isotope of containing 8 neutrons. (ii) - isotope of containing 9 neutrons. (iii) - isotope of containing 10 neutrons.
