chmvijay · Answer

as you go from top to bottom density increases !!

chmvijay · Answer

you want to compare the density of 2A and 1A group??

anonymous · Answer

this is the question i was given to answer by my professor! word for word

anonymous · Answer

about which trend U r supposed to ask...
however in the group the nuclear charge density inc. and in period only density inc.

anonymous · Answer

huh? @moezhaxxan

wat do u mean by ''huh''???

anonymous · Answer

'about which trend U r supposed to ask'

anonymous · Answer

density????

anonymous · Answer

yes density

chmvijay · Answer

compared to the density of 1A group in the same period are lower than the density of 2 A groups :)

^ this is true, for example the ionic radius of Mg2+ is smaller than Li+ so they can "pack" closer together.
