K - 39
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.
To determine the appropriate nomenclature for an isotope, one must consider the element symbol followed by the mass number of the isotope. The mass number is the sum of protons and neutrons in the nucleus of the atom. This information is typically written as Element Symbol - Mass Number.
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.
Potassium has three naturally occurring isotopes: potassium-39, potassium-40, and potassium-41. The most common isotope is potassium-39, which makes up about 93% of naturally occurring potassium.
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.
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.
'Na' is the atomic notation of sodium. Hope this helps :)
