Best ResponseYou've already chosen the best response.1Density increases. Atomic radius decreases from left to right across a period because: 1) Electrons are being "added" into the same shell, (you know that the shell number doesn't increase across a period) 2) The proton number and number of electrons increases across a period, this causes greater attractive force between positive and negative charges, resulting in decrease in atomic radius as mass increases, therefore greater density.

Best ResponseYou've already chosen the best response.0mass increases but radius decreases since d = m/V density increases i get it thank you very much !

Best ResponseYou've already chosen the best response.0but the right side we have gases but here i think they're asking only for atom i hope, not the molecule level

Best ResponseYou've already chosen the best response.0some trend still exists, as we move from left to right, s>p>d, upto the last group in d block, the density is increasing

Best ResponseYou've already chosen the best response.0looks nonmetals have less density again breaking the general increasing density trend
