use trends within the periodic table indicate which member of each of the following pairs gives up one electron more easily:a) Mg or Al (magnesium or aluminum) b) Cadmuin or Be (Beryllium) c) S (sulphur) or Aluminum d) Te or O (teryllium or oxygen)
a) Magnesium b) Beryllium c) Aluminum d) Tellurium The Effective Nuclear Charge is the force that the nucleus exerts on it's last electronHence, the stronger the force, the harder it is to rip off the electronThe Effective Nuclear Charge INCREASES from left to right, within a period, and from bottom to top within a groupSo the elements further to the left and down in the periodic table are more likely to give up their last electrons, since the effective nuclear charge is weaker.
