Answer:
Methane
Explanation:
Alkanes have the molecular formula of "CnH2n+2" which means for every carbon molecule there are two hydrogens plus two more. For example when there is one Carbon there are four hydrogens, this molecule is known as "Methane"
C since they’re very acidic they stay with red colours or even orange
Because the calcium ion donates two electrons to achieve the stable state. So the layer of electrons decrease form 4 layers(2,8,8,2) to 3 layers(2,8,8). Thus, the radius of a calcium ion is smaller than a calcium atom.
