What is the valency of Sulphur?
2 electrons
The valency of the element represents the number of bonds that an atom can form as part of a compound. The electronic configuration of sulfur is (S) [Ne] 3s1 . So in order to achieve stability, sulfur has to gain 2 electrons. Therefore, the valency of sulphur is 2.
What is the of Sulphur in sulphuric acid?
\% of sulphur=mass of sulphurtotal mass of the compound×100=3298×100=32.65\%
How do you find the valency of H2SO4?
The O is -2 and there are 4 of them for a total of -8. So the S has to be +6 in order to make the entire compound neutral. So then you have +2 for H, +6 for S and -8 for the O. This is the valency for H2SO4.
What is the valency of Sulphur in Sulphur dioxide?
In Sulphur dioxide, Sulphur is bonded to 2 oxygen atoms. Oxygen is more electronegative than Sulphur and thus, shows a fixed valency of 2. As a result each oxygen forms two bonds with the Sulphur atom making its valency 4.
What is valency of argon?
18 0

| Scandium | 21 | 3 |
Why sulphur has three valency?
We know that oxygen atoms have a valency of 2. It has 6 atoms in the outermost shell and it needs only two electrons from another atom in bonding to complete its octet. The total valency of three oxygen atoms is -6. Hence in sulphur trioxide the valency of sulphur is +6 to satisfy the -6 valency of three oxygen atoms.
How do you make sulfuric acid from Sulphur?
Sulphuric acid by contact process
- Step 1: Make sulphur dioxide.
- Step 2: Convert sulphur dioxide into sulphur trioxide (the reversible reaction at the heart of the process)
- Step 3: Convert sulphur trioxide into concentrated sulphuric acid.
What is the valence electron of H2SO4?
H2SO4 Step 8
| Total Valence Electrons | 32 |
|---|---|
| Used so Far | 6(2)+2(4)+2(6) = 32 |
| Remaining | 0 |
Does sulphur show variable valency?
Oxygen is divalent, but sulphur exhibits variable valency of 2, 4 and 6 since the atomic radius of sulphur is larger than that of oxygen, because of the presence of d-orbitals.
What is the valency of argon?
Valency Chart of Elements (first thirty)
| Element | Atomic Number | Valency |
|---|---|---|
| Phosphorus | 15 | 3 |
| Sulphur | 16 | 2 |
| Chlorine | 17 | 1 |
| Argon | 18 | 0 |
How do you calculate the valency of Argon?
General Science But argon is a noble gas and hence has a complete outermost shell. Thus it needs to accept or donate 0 electron to complete its octet. Hence the valency of argon is 0.
