Isotopes of an element have a different number of neutrons. For example Uranium-235 and Uranium-238 look chemically identical but 238U atom is slightly more massive due to the three extra neutrons.
Atoms of the same element that differ in number of neutrons
radioactive decay
All isotopes of an element have the same number of protons, otherwise they would not be the same element. What varies is the number of neutrons, they can be more or less than in the stable isotope(s) of the element.
Isotopes of a chemical element have the same number of protons and electrons but a different number of neutrons.A radioactive isotope is unstable and can emit nuclear radiations.
An atom with a different number of neutrons is called an isotope. Isotopes of the same element have the same number of protons but differ in the number of neutrons, leading to variations in atomic mass.
Atoms of the same element that differ in number of neutrons
radioactive decay
Isotopes of one particular element differ only in their number of neutrons in nucleus.
All isotopes of an element have the same number of protons, otherwise they would not be the same element. What varies is the number of neutrons, they can be more or less than in the stable isotope(s) of the element.
Isotopes of a chemical element have the same number of protons and electrons but a different number of neutrons.A radioactive isotope is unstable and can emit nuclear radiations.
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.
An isotope is an element that has the same number of protons but a different number of neutrons. Isotopes of an element have similar chemical properties but may differ in atomic mass due to their varying neutron count.
An atom with a different number of neutrons is called an isotope. Isotopes of the same element have the same number of protons but differ in the number of neutrons, leading to variations in atomic mass.
The antonym for isotope is non-isotope. An isotope refers to atoms of the same element with different numbers of neutrons, whereas non-isotope would refer to atoms of the same element having the same number of neutrons.
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.
In isotopes of a particular element, the number of neutrons differ where the number of protons and electrons remain same.
An atom with a different number of neutrons is called an isotope of the original element. Isotopes have the same number of protons (and thus the same element) but different numbers of neutrons.
