Argon has three naturally occurring isotopes: ^{36}{18}Ar, ^{38}{18}Ar, and ^{40}_{18}Ar.
The appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation A Z X is ^39_K19.
The isotope notation for sodium with 11 protons and 12 neutrons would be 23/11 Na.
The atomic number 35 corresponds to bromine, and the symbol would be 81Br.
The isotope notation for sodium with 11 protons and 12 neutrons would be Sodium-23, where the number 23 represents the sum of protons and neutrons in the nucleus.
The symbolic notation for the isotope neon-22 is ^22Ne. The "22" represents the total number of protons and neutrons in the nucleus, while the "Ne" symbolizes the element neon.
Ar 40 is the most common isotope, accounting for 99.6% of the total (by weight).
The appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation A Z X is ^39_K19.
The hyphen notation of the most common isotope of technetium, technetium-98, is 98Tc.
40K
For example a thorium isotope is Th-231 or 23190 Th.
The chemical notation is 19F.
The isotope notation for sodium with 11 protons and 12 neutrons would be 23/11 Na.
Thorium-232 is typically indicated with the notation "Th-232."
It is usually of the form 23Na where the 23 appears as a superscript.
It is usually of the form 23Na where the 23 appears as a superscript.
Ar
The atomic number 35 corresponds to bromine, and the symbol would be 81Br.
