yes,they are poisonous.
Fluorine is a pale yellow gas and very reactive. Chlorine is a pale green - which could look yellow depending on the lighting. it too is highly reactive. Of the two, you would probably be looking for fluorine as the best answer.
Chlorine is a greenish-yellow poisonous gas commonly used for disinfection and bleaching.
The Halogens are Group 17 of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and element 117 (temporarily named ununseptium [Uus]). ) Fluorine is the most active and smallest of the series. Its physical nature (a gas) and reactivity is closest to chlorine. Past this the members become liquids or solids and less reactive.
No, not all halogens are gases at room temperature. Fluorine and chlorine are gases at room temperature, bromine is a liquid, and iodine is a solid.
I think it is non-metal. This is why I think that:The state of matter is gas, so they cannot be the same.Ok, I guess I only had one reason but still. I think it is a good one reason.ans.2Fluorine is a halogen.There is no such element as flurine or flurnine.
At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
Iodine, element number 53 is the halogen (Group 17) element in period 5.
Bromine belongs to inert/rear/noble gas and other family member iodine ,fluorine and chlorine.
Halogens are fluorine, chlorine, bromine, iodine, astatine and tennessine; the identification is possible by chemical methods.
Fluorine is a pale yellow gas and very reactive. Chlorine is a pale green - which could look yellow depending on the lighting. it too is highly reactive. Of the two, you would probably be looking for fluorine as the best answer.
Group 7 of the periodic table is known as the halogens group. The gases in this group are fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2). Of these, fluorine and chlorine are diatomic gases at room temperature, while bromine is a liquid and iodine is a solid.
Refering to modern Peridic Table gas which is molecule are fluorine, chlorine, Bromine, Iodine and Astatine.
Iodine is not a "nobel" gas or even a noble gas but rather a nonmetal element that is not a gas at all at standard temperature and pressure, but a solid instead. -- Unlike the elements in the noble gas group such as neon, which are chemically very unreactive, iodine is quite reactive, like the other elements in its group such as fluorine and chlorine.

Yes. Chlorine gas is very poisonous.
Fluorine and chlorine are the gases in the fluorine family, at standard temperature and pressure.
Chlorine is a greenish-yellow poisonous gas commonly used for disinfection and bleaching.
