What are the atoms called then they have the same atomic number but different mass numbers?

They are called as isotopes in which mass number differ by emmision of radiation


How do atoms with different atomic numbers differ from each other?

Atoms with different atomic numbers have different numbers of protons in their nucleus, which determines their identity as different elements. This difference in atomic number leads to variations in their physical and chemical properties, such as size, mass, and reactivity.


What are atoms containing the same numbers of protons and different numbers of neutrons are?

Atoms containing the same number of protons but different numbers of neutrons are called isotopes. Isotopes have the same atomic number (number of protons) but differ in atomic mass due to the varying number of neutrons.


What does it mean if two atoms are isotopes?

If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.


A difference in the atomic number of atoms means the atoms are of same or diffierent elements?

Different atomic numbers represent different elements.


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.


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.


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.


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.


Can neutral atoms of the same element differ in neutrons?

Yes, neutral atoms of the same element can differ in the number of neutrons they contain. These are called isotopes, which are atoms of the same element with different numbers of neutrons. Isotopes have the same number of protons and electrons, but different numbers of neutrons.


How may atoms of the same element differ from one another?

Atoms of the same element can differ from one another in their atomic mass, which is determined by the number of neutrons in the nucleus. These variations are called isotopes. Isotopes of the same element have the same number of protons but different numbers of neutrons.


Which term describes atoms with different atomic masses due to varying numbers of neutrons?

Isotopes describe atoms with different atomic masses due to varying numbers of neutrons.
