name and give the symbol of 2 radio active elements
Helium, along with the other elements, gets its symbol from the Latin and not from English.
The element plutonium got its symbol "Pu" because it is a radioactive element named after the planet Pluto. Its discovery was highly publicized, leading to the decision to name it after Pluto and assign it the symbol "Pu" based on the first two letters of its name.
ActinidesThis is a group of elements within the periodic table and are also known as the transuranics. The name refers to those elements with increasing atomic no. from actinium, which all have similar chemical properties, like the lanthanides. The first few members of the group are the naturally occurring elements actinium, thorium, proactinium and uranium. Beyond this elements have been made artificially by radioactive bombardment. These artificial elements are unstable, some have very short lifeimes and undergo spontaneous radioactive decay.
The modern name of Eka Boron is Francium. It is a highly radioactive element with the symbol Fr and atomic number 87 in the periodic table.
Ba. You'll find this in your copy of the periodic table of the elements.
The symbol for radiation is the "radiation trefoil", and you can find it by that name. I've added a link below.
All of the actinides are radioactive, and almost all are synthetic.
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.
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.
Some radioactive elements in the periodic table are radium, uranium, plutonium, thorium, polonium, radon, francium, astatine, radium, and curium.
S is the symbol for Sulfur.
No, "Ro" is not a symbol on the periodic table of elements. Each element has a unique symbol consisting of one or two letters derived from its name.
The symbols of elements are derived from their names in various ways, often using the first letter or first two letters of the element's name, in a standardized manner based on the element's English or Latin name. For example, the symbol for sodium is Na, derived from the Latin name "natrium." You can find the symbols of elements on the periodic table of elements.
It's not a symbol is is just the name they give to the one of the stands
Tungsten is wulfram, First letter used as the elements symbol. Tungsten is obtained from the ore wolframite.
A symbol name that can be displayed on a keyboard might include the pound sign or the number symbol. The dollar symbol can also be displayed on the keyboard.
