7
Why does the atomic radius decrease as we move right of the table?
because we move outside the shell
because we add something inside the shell
because we move within a shell
none of these
8
Which of these is not a property of metalloids?
ionization energies between those of metals and nonmetals
gains electrons easily
often make good semiconductors
forms alloys with metals
9
Elements in the same group act similarly because...
