the noble gases, krypton, xenon and radon are larger than bromine
Gases that are used everyday
Most are solid. Those that are liquid are bromine, and mercury. Those that are gas are nitrogen, oxygen, fluorine, chlorine, and all the noble gases.
Not quite sure what you mean by how many gases. Bromine is a gas all by itself. It is liquid at room temperature, but it is still considered a gas. It's own element. So there is only one gas in Bromine.
noble gases are inert therefore they posses zero valency
There are 6 noble gases: helium, neon, argon, krypton, argon and radon
Noble gases doesn't form many compounds because they are extremely unreactive.
eight
There are six noble gases: helium, neon, argon, krypton, xenon and radon
There are six noble gases ,they are helium ,neon, argon, krypton, xenon and radon.
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
All noble gases have 8 valence electrons. Helium has only 2.
Counting the 4th shell orbitals and their electrons, Bromine has two 4s electrons and five 4p electrons, giving it a total of 7 valence electrons.
