19、ntains a noble gas called helium.Formerly,balloons contained hydrogen but hydrogen is very flammable and dangerous when uncontrolled.Therefore,people shifted to helium,which is safer.H elium is safe because it has the properties of the noble gases.2.People once believed that noble gases couldn,t che

20、mically react at all.For this reason,they were called inert gases.They were also clustered under Group 0 in the old periodic table because scientists believed that the gases have zero valence electrons in their outer shell.This was later proven to beuntrue when some noble gas compounds were discover

21、ed.3.The gases are elements,which share similar properties.These properties include being monoatomic,colorless,odorless,being able to conduct electricity,and having low chemical reactivity.N oble gases include H elium,N eon,Argon,Krypton,Xenon and Radon.These are all found in Group 18,in the rightmo

22、st column of the periodic table.If you look at the periodic table,you willnotice that these elements are the only ones,which do not have a charge.H eiium has the lowest molecular（分子的）weight while Radon is the heaviest.4.Remember that chemical reactions occur because atoms have“valence“electrons,whic

23、h are electrons in their outer shell.When the outer shell is”unfilied”or the required number of electrons is not yet complete,the atom is more reactive.N oble gases have a full outer shell,meaning that they have complete electrons in their outer shell.This complete number varies.For instance,the out

24、er shell of H elium has 2 valence electrons while the outer shell ofXenon has 8 electrons.N owadays,there remains to be a few noble gases because of the inherent low chemical reactivity of these said gases.5.B ecause of their properties,noble gases have many important applications.They are widely us
