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.
