Shur-Up
No compounds are metals. All metals are elements, although some metals (e.g. brass) are mixtures of metals.
The colors produced by alkali metals are typically vibrant, ranging from lilac (lithium) to deep violet (cesium) when they burn. In contrast, calcium typically produces a more subtle orange-red color when heated, which is not as intense as the colors of alkali metals.
Calcium or Potassium are not halogens but metals.
No reaction happens. Only way to get a reaction going is if you have two molecules with different Metals and Non-metals. Metals in this one are different but non-metals are not so no reaction.
Calcium nitrate can react with metals like magnesium and aluminum to form their respective nitrates. It is not typically reactive with most other metals since calcium tends to be more stable in its compounds.
Two elements that are alkaline earth metals are calcium and magnesium.
Metals are sodium, calcium and aluminium.
Both iron and calcium are metals. Iron is a transition metal, calcium is an alkaline earth metal.
