This gas is fluorine.
They are called the Halogens. They are group 17 on the periodic table. Flourine is a common example of such gas.
Yes hydrogen is a colorless odorless gas, it is the the first chemical element on the periodic table and the most reactive.
Xenon is listed as the 54th element on the periodic table. It is an inert gas but you will find it on the IUPAC Periodic Table as a "Noble Gas". It has an atomic mass of 131.3 grams.
NO!!!! They are two different elements found in the Periodic Table. Argon is a Noble(Inert) gas Potassium is a highly reactive metal, when placed in oxygen or water.
Xenon is a noble gas. It belongs to group 18 and period 5 on the periodic table.
They are called the Halogens. They are group 17 on the periodic table. Flourine is a common example of such gas.
Yes hydrogen is a colorless odorless gas, it is the the first chemical element on the periodic table and the most reactive.
No, oxygen is not the most reactive gas. On the periodic table, the reactivity of gases is symbolized in the periods, or horizontal rows, and the families, or vertical rows. Family number Eighteen is the inert gas family. Their reactivity is slight and even none at all. This means that the gases near the left side of the periodic table are more reactive.
Noble gases are least reactive because they have a full shell
Helium (He) is a noble (inert) gas placed in the group 18 of the Periodic Table.Helium falls in inert gas. It is stable and non-reactive.
nOBLE GASES
At the end of each period is a noble element. It is non-reactive.
There are 6 noble gases in periodic table. The common one is helium.

Group 17 of the Periodic Table are the Halogens: Fluorine, Chlorine, Bromine, Iodine, and Astatine. They are very reactive because they are only 1 electron away from the Noble Gas (8 electrons in the outermost shell) state.
Less reactive non metals are in the 18th group. They are noble gasses. From all the noble gasses, Xe is the only gas which forms compounds.
