Calcium shares the most characteristics with magnesium.Both belongs to 2nd group of alkaline earth metals.
Hydrogen is the only element in Group 1 that is not a metal. The other heavier metals in group one, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are all called alkali metals, which are highly reactive since they do not have a full valence shell.
Noble Gases (group 18)
The three main element groups are alkali metals , alkaline earth metals and halogen family.
The hardest element is chromium, which is in group 6.
The group of elements that share characteristics of metals and non metals is metalloids.

It is in the metals..

Potassium is a group 1/IA element, which is the alkali metals, so it shares characteristics with the rest of the elements in the group.
this element belongs in the group of metals
That element would be in the Alkali Metals (group one)
Group 11, transition metals
Metalloids
The three most general elemental groups are nonmetals, semimetals, and metals. The characteristics you've described fit the "metals" group of elements.
Francium (the element) is the heaviest element in the alkali metals group (Group I) of the periodic table.
