Neither Potassium nor Calcium is a halogen since both are metals.
Some of these metals are: Calcium, Magnesium, Sulfur, Sodium, Potassium, ...
Yes. They are because they are both are in the same group and are metals.
Calcium, Potassium, Carbon, Hydrogen....to name only a few....
francium ceasium Potassium Sodium Lithium These metals could react with calcium nitrate in a displacement reaction as they are more reactive. e.g. pottasium + calcium nitrate -> calcium + pottasium nitrate.

Calcium or Potassium are not halogens but metals.
potassiumwill share more properties with sodium because both are Alkali metals and have same number of valence electrons.
Potassium
Calcium, Potassium and sodium are metallic elements. they are considered to be very reactive, perhaps they exist in the top five- most reactive metals. Calcium and Phosphorous constitute our bones and teeth. common salt or table salt is Sodium Chloride.
Magnesium, Iron, Copper. Most reactive - least reactive.
Neither Potassium nor Calcium is a halogen since both are metals.
Both metals can lose two electrons and both metals form ions with a 2+ charge.
Most reactive metals, Zinc, being most common in practice, sodium Potassium Calcium etc
No. These are not heavy metals. They are salts of non heavy metals.
Some of these metals are: Calcium, Magnesium, Sulfur, Sodium, Potassium, ...
No. Alkali metals such as sodium and potassium are not usually considered contributors to water hardness. The alkaline earth and transition metals (such as calcium and iron) are. Potassium itself is a very soft metal that can be easily cut with a steel knife.
