NO. An element always has its own unique atomic number, because the atoms of that element all have identical amounts of protons. Counting the number of protons in a nucleus of an atom reveals the identity of the atom. So, all atoms of the same element have the same atomic number.
However atoms of one element CAN have a different masscaused by different number of neutrons in nucleus: these are called isotopes of that element.
No. The only thing that can change within an given element, is the Atomic Mass usually referred to as isotopes, which means there is a different abundance of each isotope.
For example chlorine has two isotopes one which is 75.78% and a atomic mass of 34.969 and the second is 24.22% and a atomic mass of 36.966.
Now calculate the average atomic mass and you have a answer of 35.45.

∙ 15y agoyes, they do. the atomic number is at the upper left or right hand corner of the element on the Periodic Table the atomic number is the number of protons in an element, and each element has a different number of protons. that is how they are arranged.
Wiki User
∙ 11y agoYes. They have the same number of Protons, meaning they are the same element, but have different numbers of Neutrons, so have different atomic masses. These are called isotopes of that element.

∙ 11y agoYes they are called isotopes they have the same number of protons and electrons but different number of neutrons which makes them unstable in some cases.

Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
The various atomic weights of the same element are called?
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
How are the isotopes of an element are alike and how are they different?
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
Do Isotopes of uranium have different atomic numbers?
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
Why are the atomic mass numbers of an element not hole numbers?
Its the average of the weight of the different isotopes of that element.
Define the term isotope explain how two isotopes of an element are different?
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^
Do isotopes of an element have the same atomic mass but different atomic number?
The different mass numbers are due to different numbers of neutrons.
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
How do you know the difference between isotopes and an element?
Isotopes are atoms of an element having different number of electrons.
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
The various atomic weights of the same element are called?
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
Isotopes of uncharged elements have different numbers of which of these?
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Which isotopes of uncharged elements have different numbers?
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
