Uranium isotopes
Isotopes differ by the number of protons.
Isotope.
They have different number of neutrons
Different isotopes of an element differ in the number of neutrons and thus in their atomic weight.
isotopes of a given element differ in the number of neutrons they have.
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.
They have the same formulas but different organic structures.
differ from what?
Different isotopes of an element have the same number of protons but differ in the number of neutrons in their nuclei. This results in different atomic weights for each isotope. Isotopes of an element may exhibit different physical properties and may have varying degrees of stability.
Isotopes are two or more forms of the same chemical element that differ in atomic mass due to having a different number of neutrons in their nuclei. These isotopes of an element have the same number of protons and electrons but vary in their overall mass.
Isotopes of the same element have different number of neutrons.
