Periodicity-trends of the elements on the periodic table

Periodicity-trends of the elements on the periodic table. Mr. Guerrero LFHS. The 2 reasons for most trends:. 1) Effective Nuclear Charge( Zeff )- the ability(pull) of the nucleus to attract its valence electrons. This increases with increasing numbers of protons in the nucleus.
