False.
elements are isotopes, when different atoms of the same element have different number of neutrons
Elements with isotopic atoms? An isotope is the same form of an element, but with a different number of neutrons. An element with isotopes/"isotopic atoms" is simply an element with isotopes.
The atomic number of the isotopes of an element is identical; the mass number is different.
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
You must check the mass number (A) - its place in the element's symbol (E) is: AE If A is different in the showed elements that means the these are different isotopes.
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
The isotopes of the same element have an identical number of protons and electrons; the number of neutrons is different.
They are called isotopes. They have different mass nmbers because they have a different number of neutrons.
Isotopes of elements have different atomic mass'.
element vs isotopes
The isotopes of hydrogen are all hydrogen. They have the same number of protons, or atomic number, which is unique to each element.
