Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
Isotopes differ in the number of neutrons they possess.
Specific for a chemical element is the number of protons.
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
Isotopes of elements have differing numbers of neutrons.
The isotopes can have different numbers of neutrons and mass.
No. If they had different atomic numbers, they would not be the same atom and would be different elements. Different isotopes have different mass numbers.
Such isotopes not only can but must have different numbers of neutrons.
The atomic number of the isotopes of an element is identical; the mass number is different.
isotopes are elements of the atomic number but have different mass numbers.
They have different numbers of protons and nuetrons, and feature a different number of electrons at an uncharged state.
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
They have different numbers of neutrons, which changes the atomic mass and nuclear properties.
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
All the isotopes of an element have the same number of electrons and protons; different is only the number of neutrons.
Yes atoms of the sane element with different numbers of neutrons are known as isotopes.
It can if isotopes are present. They can contain different numbers of neutrons in the nucleus.
On most periodic tables, only elements that do not occur naturally have mass numbers that are whole numbers. All isotopes of these elements are radioactive, and because the isotopes almost always decay at different rates, there is no stable ratio among the isotopes, as there is with elements that have non-radioactive isotopes. On most periodic tables, such mass numbers are listed within parentheses, and a footnote explains that these are the mass numbers of the longest-lived isotope of the element that is known.
A rule doesn't exist; the number of isotopes is a characteristic for each chemical element. Isotopes are stable or unstable, radioactive.
different isotopes of the same element have different numbers of what?
Elements can exist in the form of different isotopes. Isotopes of the same element have the same number of protons in their nuclei but have different numbers of neutrons. The first gives them the same atomic number and chemical properties while the second gives them different atomic weights.
Most elements have different isotopes, with different numbers of neutrons. Once source to get more information about the cobalt isotopes is the Wikipedia article on Cobalt - look for the section on isotopes.
This may be a matter of how the word atom is defined. Most elements have isotopes which have different numbers of neutrons in an otherwise identical atom. So, if isotopes are different types of atoms then elements can have more than one type of atom. If isotopes are not different types of atoms then elements can only have one type of atom.
Mass numbers of isotopes are different.
