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).

How do you take out valency an element?
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)
The atomic number of oxygen means what?
Oxygen is a none metal element. atomic number of it is 8.
What element has an atomic number of eight?
Oxygen is a gas element. atomic number of it is 8.
What does an atoms atomic number tell about the atom?
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.
What elements have the atomic number 12 and atomic mass 8?
Atomic Mass 8 Beryllium Atomic Number Magnesium there is no element that has both
Why does an element have an atomic number of 8?
Oxygen is a non metal element. Atomic number of it is 8.
What number of protons in one atom of an element is that element's?
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.

What is the atomic number of the element oxygen?
Oxygen is a non metal element with atomic number of 8.
Why does an element have the atomic number of 8?
Oxygen has atomic number 8. It is placed in group-16.
What is the atomic number of an atom that has 10 neutrons 8 protons and 8 electrons?
It would be 8, and it is the element oxygen. The atomic number is simply the number of protons in the element.
How many electrons are in an oxygen atom that hasan atomic number of 8?
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).
