Which option best describes a similarity and a difference between isotopes of an element?

A similarity between isotopes of an element is that they all have the same number of protons, which means they share the same atomic number and chemical properties. A key difference, however, is that isotopes have varying numbers of neutrons, leading to differences in atomic mass and stability, which can result in some isotopes being radioactive while others are stable.


Why do the isotopes of hydrogen have a greater ratio of mass difference than the ratios for any other isotopes of other elements?

The isotopes of hydrogen have a greater ratio of mass difference because hydrogen has the smallest atomic mass compared to other elements. Since the mass of hydrogen isotopes differs significantly (H-1, H-2, and H-3), the ratio of their mass difference is also relatively larger. This makes the difference in mass between hydrogen isotopes more pronounced compared to isotopes of other elements, which have higher atomic masses.


What determines the difference between isotopes of C-12m C-13 and 14?

These isotopes have a different number of neutrons.An isomer C-12m doesn't exist; the isotope is C-12.


What is the density of the isotope 190Pt?

The density of platinumi s 21,45 g/cm3. The difference in density between isotopes is not significant.


What causes the difference in mass between the two isotopes of carbon?

The difference in mass between the two isotopes of carbon, carbon-12 and carbon-14, is primarily due to the number of neutrons in their nuclei. Carbon-12 has six protons and six neutrons, while carbon-14 has six protons and eight neutrons. The additional neutrons in carbon-14 increase its overall mass, resulting in the isotopes having different atomic weights. This difference in neutron count is what distinguishes their isotopic forms.

What is the difference between mendelevium-256 and mendelevium-258?

They are the isotopes. Because of the difference in the number of neutrons by 2 they have been named that way.


What is the number of neutrons in a single atom of mendelevium?

The number of neutrons is equal to the atomic mass of an isotope minus the atomic number (or the protons number) of the element. The atomic number of mendelevium is 101 and Md has isotopes with atomic masses between 245 and 260.

How do scientist tell the different between two isotopes of the same element?

scientists Can tell the difference between two isotopes of the same element because, isotopes of the same elements always have the same number of protons.


Can 2 isotopes of the same element differ in the number of electrons?

No. The only difference between 2 isotopes of the same element is the number of neutrons.


The main difference between isotopes of the same element has to dowith the number of?

The main difference between isotopes of the same element is the number of neutrons in the nucleus. Isotopes have the same number of protons and electrons but different numbers of neutrons, which affects their atomic mass.
