Respuesta :
atoms are made of 3 types of subatomic particles that are electrons, protons and neutrons.
the number of protons in the atom is called the atomic number. the atomic number is characteristic of the element.
the mass number is the sum of the number of protons and neutrons. Since protons and neutrons both have similar masses and they are located in the nucleus, the mass of the atom is the sum of protons and neutrons.
Isotopes are when 2 atoms of the same element have different number of neutrons. Therefore atomic number is the same but mass number is different as the number of neutrons vary.
correct answer for the difference between isotopes is
d)They have different numbers of neutrons and different mass numbers.

Boron occurs naturally as two isotopes that is they have the same number of protons and different numbers of neutrons with different atomic charges. Option D is correct.
What are isotopes?
These are the variations of elements having the same number of protons and electrons and different numbers of neutrons. As they are neutral in charge and their mass is totally negligible as compared to the mass of proton as they both are located at the center of the atom
The center of the atom is the nucleus as there are some more species of element isobars isotones isoelectronic. Isobars are those species that have the same neutronic numbers with different photonic and electronic numbers
The isotopes of boron are boron10, boron12, boron14, etc. .Carbon is another compound that is having 3 isotopes carbon12 carbon13, and caobon14. But mostly their properties are the same with a little difference between them
Therefore, the correct option is D.
