If a sample of an element contains atoms of different mass numbers, the name of the element followed by a hyphen and the mass number is the name of an isotope of the element.

Does an isotope of an element have a different atomic mass?

Yes, isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This is why the atomic mass on the periodic table is often listed as a range for an element.


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 element has the atomic number for 3.14?

No element has this atomic number. All atomic numbers are whole numbers.


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 atomic property is different in each isotope of an element?

The number of neutrons in the nucleus is different in each isotope of an element. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to variations in atomic mass.


What is it called when they have same atomic number but different mass?

They are called isotopes of the same element


How can different atoms of the same element have the same atomic number but can have different mass numbers?

They have different numbers of neutrons.


What are atoms that have the same atomic number but different neutron numbers?

Atoms that have the same atomic number but different neutron numbers are known as isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in their atomic mass.


What describes an atomic number of an element?

The atomic number of an element is the number of protons in the nucleus of an atom of that element. It determines the unique identity of an element and its position on the periodic table. Elements with the same atomic number belong to the same element, while elements with different atomic numbers are different elements.


Isotopes of the same element have differnt?

Isotopes of the same element have different numbers of neutrons in their atomic nuclei. This results in isotopes having slightly different atomic masses while maintaining the same number of protons (which determines the element's identity).


Do some atoms have more or fewer protons than will other atoms of the same element?

No. The atomic number of an element is determined by its number of protons. If two atoms have different numbers of protons, they have different atomic numbers and are different elements.
