Tin.
Francium.
Tin (Sn) has the most number of isotopes with over 30 known isotopes. This is because it has a large atomic number and therefore a greater range of possible isotopes.
Isotopes of the same element have different number of neutrons.
Isotopes of the same element have a different number of neutrons.
The atomic number is the same for the all isotopes of a chemical element.
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
The atomic number is the same for the isotopes of a chemical element.
neutrons
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number of neutrons.
This statement is incorrect. Isotopes of an element have the same number of protons but differ in their number of neutrons. Rubidium, specifically, has two stable isotopes: Rb-85 and Rb-87, which both have 37 protons but different numbers of neutrons.
The number of neutrons is different in isotopes of an element. Isotopes of the same element have the same number of protons (which defines the element) but different numbers of neutrons. This variation in neutron number gives rise to different atomic masses among isotopes of an element.
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
