Hyphen Notation is the name of the element, then hyphen, then the mass number written after the element. For example, Chlorine-35.
Extract from the mass number (in the hyphen notation) the atomic number.
If you think to the notation of an isotope, see an example with deuterium: 21H - where 2 is the mass number of deuterium and 1 is the atomic number.
You write the Symbol of the element, a hyphen and then the mass number. i.e. C-14
The chemical symbol of plutonium is Pu.
Element - Atomic Mass # Example: Carbon - 12
This symbol is Tc-99m.
Examples: francium-223 or Fr-223.
H-1 h-2 h-3
An atomic number of 2 makes the element helium; therefore, the notation is He-4.
These symbols are:5626U and Fe-56.
28SiSilicon-14The nuclear symbol and hyphen notation for 26 protons and 30 neutrons is 26Fe, iron-56. A proton is a particle that has a positive charge and is found in the nucleus of an atom.
Li-7. Tizz the element then a dersh (dash) then the atermic merss (atomic mass).
Helium is a non metal element. Mass number of it is 4.
im not quite sure what you mean but if you mean like the abbreviation eg: Oxygen=O Nickel=Ni
138 56Ba, barium-138 D:< >:U
