Density is the mass of a unit volume of the element and is commonly expressed in units of g/cm 3. Web12: THE PERIODIC TABLE (SUGGESTED SOLUTIONS) Structured / Free Response Questions 1 (i) A l. A l has lower first ionisation energy than Mg. The 3p electron in A l is at a higher energy level than the 3s electron in Mg and is hence less strongly attracted by nucleus. Hence less energy is needed to remove the 3p electron in A l.
