valency
In other words, valence value is the combining capacity of and element.
YES
No. Carbon is oxidized. The only element that would be reduced when combining with oxygen would be fluorine.
The Pauling electronegativity of phosphorous is 2,19 so it is sufficiently reactive.
Yes Another answer: No. Combining capacity is related to the fill level of the atom's valence shell, while the charge has to do with the balance between protons and electrons. The two things are not the same.
calcium combines well with other rocks
hybridization
Elements from a family have similar chemical properties.
