Atomic Mass minus atomic number.

This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons.

The atomic number of an element is simply the number of protons in the atom.

So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.

How do you determine the isotope?

Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.


Isotopes of an element have a different number of?

neutrons


What are element that differ in the number of neutrons known as?

Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.


Atoms of same chemical element that have different atomic mass are known as?

Isotopes. They differ in the number of neutrons in the nucleus.


What are Atoms that vary in the number of neutrons found in their nuclei called?

Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.


What does the number of neutrons determine?

The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.


What do Carbon isotopes have in common?

All carbon isotopes have the same number of neutrons.


What are facts about isotopes?

What do isotopes depend on?

Isotopes have different number of neutrons.


What determines the different isotopes from an atom?

The name of the element and the mass number (number of protons + neutrons) it is written e.g Uranium-235 or symbolically 235U


Isotopes have a different number of what?

Neutrons of course?!


Isotopes of an element differ from each other in the number of?

Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
