ok, im using CC to learn chemistry. lame , but necessary.
regarding periodic trends..
whats the 'shielding effect'?
is it that the atom just gets fatter/bigger because its getting more valence orbitals filled as you go along the periodic table?
and to clarify, z effect is just atomic#-#electrons so you get the idea that the inner electrons experience a greater net attration while the outermost electrons experience a smaller attraction because the negative charges of the inside electrons counter the nucleus' positive charge - right?
