Co,Ni makes cations of different colours. So they make easily identifiable compounds. Elements in the d group make colourful cations.
Group 1 elements are highly reactive metals that readily form compounds to achieve a stable electron configuration. Group 7 elements (halogens) have high electronegativity and easily react with other elements to form compounds. This reactivity makes them commonly found as compounds rather than in their pure elemental form.
Copper, Silver, and Gold occur as elements instead of compounds.
Compounds are formed from elements.
True. Compounds do not have the same properties as the elements that form them.

Co,Ni makes cations of different colours. So they make easily identifiable compounds. Elements in the d group make colourful cations.
compound
In terms of the total mass of the universe, it is single elements.
two or more different elements
Chemical compounds are formed from chemical elements.
There is no general relationship.
Elements and compounds
Group 1 elements are highly reactive metals that readily form compounds to achieve a stable electron configuration. Group 7 elements (halogens) have high electronegativity and easily react with other elements to form compounds. This reactivity makes them commonly found as compounds rather than in their pure elemental form.
Elements become compounds after chemical reactions.
They use colourful and bright colours!
Because they have interlocking electrons as the different elements' electrons have been 'tangled'
