Question

use the information in the table to answer the question that follows. atomic information
sample number of protons number of neutrons
1 36 44
2 36 46
3 36 48
4 36 50
which statement best describes these samples? the chemical properties are different for each element. the atomic number is different for each element. they are allotropes of the same element. they are isotopes of the same element.

Explanation:

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. Here, all samples have 36 protons but different numbers of neutrons. Allotropes are different forms of the same element in the same physical state and are not relevant here. Chemical properties are mainly determined by the number of protons (and electrons in a neutral atom), so they are similar for isotopes of the same element. The atomic number is equal to the number of protons, so it is the same for all these samples.

Answer:

They are isotopes of the same element.
