boron occurs naturally as two isotopes. what is the difference between these isotopes? they have different numbers of electrons and different charges. they have different numbers of neutrons and different charges. they have different numbers of protons and different mass numbers. they have different numbers of neutrons and different mass numbers.

boron occurs naturally as two isotopes. what is the difference between these isotopes? they have different numbers of electrons and different charges. they have different numbers of neutrons and different charges. they have different numbers of protons and different mass numbers. they have different numbers of neutrons and different mass numbers.

Answer

Brief Explanations:

Isotopes of an element have the same number of protons (which defines the element), but different numbers of neutrons. The mass number is the sum of protons and neutrons, so different - neutron numbers mean different mass numbers. They are neutral species (same number of electrons as protons in neutral atoms), so charges are not different.

Answer:

They have different numbers of neutrons and different mass numbers.
