A student makes four statements about the noble gases.
Statement 1: every noble gas atom has eight electrons in its outer shell
Statement 2: noble gases exist as single atoms because their atoms do not readily share electrons
Statement 3: the boiling points rise down the group because the covalent bonds between the atoms become stronger
Statement 4: noble gases are unreactive because their atoms have stable electron arrangements, so they do not readily lose or gain electrons
Which statements are correct?
