What do period members have in common in the periodic table?

Answer 1

There are seven periods in the Periodic Table--represented by seven horizontal groups. Each group is organized in such a way that is meant to illustrate similar chemical behavior in the elements. For instance, period 2 elements obey the ocet rule, which means that they need 8 electrons to complete (or stabilize) their valance shell.

Answer 2

Elements in the same group of periodic table have same number outer valence electrons due to which their physical and chemical properties are almost similar,like * atomic size * ionisation enthalpy * electron gain enthalpy * melting point * boiling point * electronegativity * metallic/non metallic character * oxidising/reducing character * bond dissociation enthalpy However some anomalies are present.

Answer 3

Elements in the same period show trends in atomic radius, ionization energy, electron affinity, and electronegativity
