What else can I help you with?
What is a radioactive nonmetal At Po Ra Xe none of these?
Astatine is a radioactive, natural element and also a nonmetal similar to halogens.
What are three halogens?
The halogens are: fluorine, chlorine, bromine, iodine, and astatine - although astatine only occurs in extremely minute quantities as part of the decay chain of some radioactive elements like uranium and thorium.
Are halogens more reactive than actinides?
Halogens are generally more reactive than actinides. Halogens are a group of elements known for their high reactivity due to their ability to easily gain an electron and form negative ions. Actinides, on the other hand, are a series of radioactive elements that tend to be less reactive overall.
Elements in Group 17 are all called?
Halogens Apex ;)
Is tellurium radioactive?
Tellurium is radioactive, though there are stable isotopes. The radioactive isotopes found in nature account for more than two thirds of any normal sample. Additional synthetic radioactive isotopes exist.
Why are halogens known as salts?
Halogens are not salts but they are chemical elements; halogens can form salts reacting with metals.
Are halogens reactive?
Yes, halogens are extremely reactive.
How are halogens like metals?
Halogens are not like metals. Halogens are elements missing one electron for full valency.
Which non-metals are chemically most reactive?
halogens
What is another name for the group 17 elements?
Another name for Group 17 (VIIA) Elements is Halogens.
How do psychical and chemical properties of halogens compare with those of the inert gas?
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
Is halogen an element belonging to group 17 of the periodic table?
halogens are the element placed in the 17th group of the period table. they have valency 1 and are the most reactive and the most electronegative elements.Halogens include flourine,chlorine,bromine,iodine and astatine (the radioactive element) their electronegativity decreases down the group. halogens are also called as salt forming elements.
