molecules of two different compounds contain the same number of atoms of each element but have different arrangement of atoms. which term correctly describes these two substances?
a) isomers
b) isotopes
c) polymers
d) none of the above
To determine which term correctly describes two substances that contain the same number of atoms of each element but have different arrangements of atoms, let's break down the options:
a) Isomers - Isomers are compounds that have the same molecular formula but differ in their spatial arrangement or structure. Since the molecules in question have the same number of atoms of each element but differ in the arrangement of atoms, the term "isomers" accurately describes these substances.
b) Isotopes - Isotopes refer to atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. This term does not apply to the situation described.
c) Polymers - Polymers are large molecules composed of repeating subunits known as monomers. The arrangement of atoms in these substances may vary, but the fact that the different compounds in question have the same number of atoms of each element makes the term "polymers" inappropriate.
d) None of the above - Based on the explanations above, we can conclude that option d) "None of the above" is not the correct answer.
Therefore, the correct term that describes two substances with the same number of atoms of each element but different arrangement of atoms is: a) Isomers.
