Li-7. Tizz the element then a dersh (dash) then the atermic merss (atomic mass).
im not quite sure what you mean but if you mean like the abbreviation eg: Oxygen=O Nickel=Ni
argon's atomic number is 18
The electron configuration of plutonium is [Rn]5f67s2.
Example for the uranium isotope 235: 23592U where 235 is the mass number and 92 is the atomic number. Note 92 is under 235 but I cannot write here.
Extract from the mass number (in the hyphen notation) the atomic number.
Rn-222
Ge-73
Element - Atomic Mass # Example: Carbon - 12
This symbol is Tc-99m.
Examples: francium-223 or Fr-223.
H-1 h-2 h-3
Hyphen Notation is the name of the element, then hyphen, then the mass number written after the element. For example, Chlorine-35.
P-33
These symbols are:5626U and Fe-56.
