Concept explainers
Interpretation: Option representing a pair of isotopes needs to be identified.
Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.
Answer to Problem 4STP
Correct answer: The correct option is C.
Explanation of Solution
Reason for correct option:
An atom has a nucleus with a positive charge due to its protons and has electrons in the space surrounding the nucleus at relatively large distance from it. Isotopes are atoms of same element with different neutrons.
Isotopes of an element will have different masses and number of neutrons and also, it has same number of electrons, protons.
According to the definition of isotopes, carbon
Reasons for incorrect options:
Option A: This option does not represent a pair of isotopes. So, this is an incorrect option.
Option B: This option does not represent a pair of isotopes. So, this is an incorrect option.
Option D: This option does not represent a pair of isotopes. So, this is an incorrect option.
