This symbol is Tc-99m.
The hyphen notation for Radon is Rn-222.
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.
P-33
These symbols are:5626U and Fe-56.
Hyphen notation for isotopes involves writing the element name or symbol followed by a hyphen and then the mass number. For example, carbon-14 is written as C-14 and uranium-235 is written as U-235. This notation helps differentiate between different isotopes of the same element.
The hyphen notation for Radon is Rn-222.
Hyphen Notation is the name of the element, then hyphen, then the mass number written after the element. For example, Chlorine-35.
Examples: francium-223 or Fr-223.
Extract from the mass number (in the hyphen notation) the atomic number.
Hyphen notation is a method used in chemistry to represent isotopes of an element. It involves writing the element's name followed by the mass number of the isotope as a superscript and the atomic number as a subscript, separated by a hyphen. For example, hydrogen-2 (deuterium) is represented as "H-2" in hyphen notation.
Argon's hyphen notation is 1s2-2s2-2p6-3s2-3p6. This notation represents the electron configuration of argon, showing the distribution of electrons in its various atomic orbitals.
Li-7. Tizz the element then a dersh (dash) then the atermic merss (atomic mass).
Note that since all carbon isotopes have an atomic number of 6, it is not necessary to state the atomic number; the fact that it is carbon means that it has the atomic number 6. So the isotope with a mass number of 14 is called carbon 14. As a symbol, it is C with a superscript 14 (which I am not able to type).
Sodium has several isotopes, but the most common ones are sodium-23 and sodium-22. The hyphen notation for sodium-23 is 23-Na and for sodium-22 is 22-Na.
im not quite sure what you mean but if you mean like the abbreviation eg: Oxygen=O Nickel=Ni
Ge-73
