Introduction:
Atoms are the smallest particles that exhibit some chemical properties and consist of protons, neutrons, and electrons. The protons and neutrons are present in the nucleus and electrons keep revolving around the nucleus in an orbit.
Answer to Problem 1DYB
Correct answer:
The isotopes have a different number of neutrons. Therefore, option c. is correct.
Explanation of Solution
Reason for the correct statement:
Option c. is given as “isotopes”. The isotopes are the different atoms of the same element that have the same number of protons and electrons but differ in the number of neutrons and atomic masses.
Hence, option c. is correct.
Reasons for incorrect statements:
Option a. is given as “isomers”. The isomers have same atomic masses and it is a molecule that has a same molecular formula but differs in the arrangement of atoms. Hence, option a. is incorrect.
Option b. is given as “ions”. Ions are charged atom and do not have an equal number of electrons and protons. Hence, option b. is incorrect.
Option d. is given as “organic atoms”. These are the atoms like carbon, oxygen, nitrogen, hydrogen, and phosphorus. These atoms form organic molecules. The protons, neutrons, and electrons are the same as an ordinary atom. Hence, option d. is incorrect.
Hence, options a., b., and d. are incorrect.
The isotopes are the atoms that have different atomic masses due to the difference in neutrons and have similar electrons and protons.
