Can you give the table of the oxidation numbers of the element of different groups
Answer
The table lists the typical oxidation numbers for elements in different groups.
Explanation
Solution
Below is a concise table summarizing the common oxidation numbers for elements in various groups. Note that many elements (especially the transition metals) may show multiple oxidation states depending on the chemical environment.
Group | Common Oxidation Number(s) |
---|---|
IA | +1 |
IIA | +2 |
IIIA | +3 |
IVA | +4; also can show +2, –2, –4 |
VA | +5; sometimes +3 and –3 |
VIA | +6; can also be +4 and +2; note that in binary compounds –2 |
VIIA | +7; also can appear as +5, +3, +1; or –1 in halides |
0 (VIIIA) | 0 (noble gases generally do not form bonds except under extreme conditions) |
For Transition Metals (d-block):
- Group IB (e.g., Cu, Ag): Mainly +1 (also +2 occasionally)
- Group IIB (e.g., Zn, Cd): Almost exclusively +2
- Group III B: +3
- Group IV B: Commonly +4 (also +2 in some cases)
- Group V B: Can show +5, with possible +3 and +2
- Group VI B (e.g., Cr, Mo, W): Typically +6 but may also be found in +4, +3, +2 states
- Groups VII B, VIII B, IX B, X B: Often show multiple oxidation states (commonly +2 and +3, with others depending on the element)
- For main-group metals, the oxidation number usually corresponds to the group number (with exceptions as noted).
- Transition metals show variable oxidation states due to electron arrangements in d and s orbitals.
