The electronic configurations of the elements in group 1: The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in their outer...
Elements in group 1 and group 2 are metals. Atoms of group 1 elements have one electron in their outer shell, and atoms of group 2 elements have two electrons in their outer shell.
Dalton (1803) arranged known elements in order of atomic weights. Newlands (1865) noticed that every eighth element, in order of atomic mass, repeated similar properties. Mendeleev swapped the order of atomic weights in order to fit elements better into groups of similar properties.
This page explores the trends in some atomic and physical properties of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium. You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity and physical properties.
