group 0 elements

are group 0 elements metals or non metals?

non metals

what are group 0 elements also known as?

noble gases

are group 0 elements reactive or not?

they’re highly unreactive

why are the noble gases called group 0?

they have 0 reactivity; they don’t react with other elements to form chemical compounds

why are noble gases unreactive?

the electronic structure is stable; they have a full outer shell so they don’t need to react to gain, lose or share electrons

why do noble gases exist as single atoms?

they don’t form molecules; as noble gases have a full outer shell of electrons, they don’t need to share electrons for more stability

does the boiling point increase or decrease down group 0?

increases

why does the boiling point increase?

between atoms of an element, there’s weak attractive forces known as intermolecular forces; when atoms are boiled or melted, these intermolecular forces are broken & as you go down group 0, the atoms increase in size and there’s more electron shells. the intermolecular forces become stronger so more energy is required to break the forces and so a higher boiling point
