name and give the symbol of 2 radio active elements
Hydrogen! :)
The periodic table lists elements by their NAME and by their SYMBOL (an abbreviation for uses including the display of chemical formulas). Element name : "IRON" / Element symbol "Fe" (from the Latin name "ferrum")
element symbols are abbreviation of elements name like gold's symbol is Au. always first letter is cap. and second is lowered i hope this helped you.
While giving symbols to the elements the first letter of the name of the element was used. But in case of two or more elements with same initial the next elements were given symbols containing first two letters. Since boron has symbol B, so bromine got the symbol Br.
S is the symbol of Sulphur and P is the symbol for Phosphorus. Since the symbols of two elements cannot be the same, the symbol of Sodium is Na (taken from its latin name "natrium") and that of potassium is K (taken from its latin name '"kalium").
Hydrogen
Sounds to me like radiation from a radioactive isotope. The breaking down part would be the half-life. But the isotope won't completely break down. Only until it reaches a stable form. Such as, radium-226 decays finally to lead-206. During the process it emits charged Alpha particles.
All of the actinides are radioactive, and almost all are synthetic.
The symbol for radiation is the "radiation trefoil", and you can find it by that name. I've added a link below.
Fr is the symbol for the radioactive element francium.
Na is the symbol of sodium and Cl is the symbol of chlorine.
The elements that are newly discovered or are radioactive and found in traces are usually named according to a system of nomenclature based on their atomic nos.Eg. element 243 (if discovered, some day) will be named as biquadtrium (Bqt) which is NOT the proper symbol/name for the element.
Hydrogen! :)
S is the symbol for Sulfur.
Lead. The symbol is derived from its Latin name; Plumbum
The symbol of an element is an abbreviation for the element's name, and it is derived either from the English or the Latin name. For example: Bromine's symbol is Br. The symbol inside an element's square is the element's atomic number, or the number of protons and neutrons in the element.
Na, the symbol for sodium. Natrium is the Latin name of sodium.
