Two, unless an oxygen atom is bonded to another oxygen atom or to a fluorine atom.
it does. for example in H2O oxygen has a valency 2 while in hydrogen peroxide H2O2 oxygen exhibits valency 1
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).
Electron configuration for oxygen (O) is 1s2 2s2 2p4. The valency is 2-.
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)
To find the valency of a mixture or compound, you need to know the individual valencies of the elements involved. Valency is determined by the number of electrons an atom gains, loses, or shares to achieve a stable electron configuration. For example, in water (H2O), hydrogen has a valency of +1 and oxygen has a valency of -2, resulting in a compound with a total valency of zero.
The co-valency of phosphorus in P2O5 is 5. This is because each phosphorus atom forms 5 covalent bonds with oxygen atoms in the molecule.

The valency of oxygen in this scenario would be 2. Oxygen typically has a valency of 2 when it forms compounds.
Oxygen has a valency of 2. This means that it can form up to two bonds with other elements in chemical compounds.
The valency of oxygen in suboxides can vary, but it is typically less than its usual valency of 2 in oxides. Suboxides contain oxygen atoms with a valency of 1 or less, resulting in a lower overall valency for oxygen in these compounds.
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).
The valency of oxygen is two because oxygen typically forms covalent bonds by sharing two electrons with other atoms. This allows oxygen to achieve a stable octet configuration, which is energetically favorable.
Electron configuration for oxygen (O) is 1s2 2s2 2p4. The valency is 2-.
S = +6 valency O = -2 valency
The valency of Cr2O7 is -6. This is because each oxygen atom has a valency of -2, giving a total valency of -14 for the seven oxygen atoms. Since the overall charge of the Cr2O7 ion is -2, the valency of the two chromium atoms must be +12 to balance out the negative charge.
The valency of phosphorus in P2O5 is +5 because each oxygen atom has a valency of -2, giving a total of -10 for the oxygen atoms. To balance the charge in the compound, the phosphorus atom must have a valency of +5.
