There are three natural isotopes.
Argon's atomic number is 18, which means it has 18 protons in its nucleus.
Isotopes. They differ in the number of neutrons in the nucleus.
Argon is very unreactive as it is a noble gas. Its common oxidation number is zero.
Isotopes differ by the number of protons.
Ar
The atomic number is the same for the isotopes of a chemical element.
Isotopes have a different number of neutrons.
Isotopes have different 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.
Isotopes
No the atomic number is same for the three isotopes of hydrogen (it is 1). The three isotopes of hydrogen differ by the number of neutrons.
The number of neutrons is different for isotopes.
