Carbon has a valency of 2, 4. Which might be useful information if it were either a) correct or b) relevant (the atomic number of carbon is 6). The element with an atomic number of 8 is oxygen, which has a valence of 2 (and a most common oxidation number of -2).
I guess, the most fundamental is their valency. This dictates how many times it can bond to other elements. Elements with the same valency often share similar properties with other elements with the same valency. The periodic table is divided into 8 rows (and a D block). Each of these 8 rows have elements with similar properties, related to their valencies.
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.

Oxygen is a non metal element. Atomic number of it is 8.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.

Oxygen has atomic number 8. It is placed in group-16.
It would be 8, and it is the element oxygen. The atomic number is simply the number of protons in the element.
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).
Oxygen is a gas element. atomic number of it is 8.
Atomic number 8 belongs to Oxygen!
