because the electronegativeties of these elements are low thy don't have much tendency to form negative ions
Carbon is a pblock element. It shows -4 to +4 oxidation numbers.
Carbon shows many numbers. the range is between -4 to=4.
CO is a harmful gas.C shows +2 in CO and it shows +4 in CO2.
Simply it is in group A4(14). And because it has 4 valence electrons which are filled in outer s and p orbitals. It shows +4 oxidation state though +2 is more stable ( Refer inert pair effect)
In the carbon group (Group 14), the elements have oxidation numbers of +4 for carbon, +2 or +4 for silicon, +2 or +4 for germanium, +2 or +4 for tin, and +2 or +4 for lead. The oxidation number can vary depending on the specific compound or ion that the element is part of.
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Acetic acid is a weak acid. c shows +3 as the oxidation number.
Carbon typically has an oxidation number of +4 when it forms covalent compounds due to sharing four electrons in its outer shell, achieving a more stable electron configuration. This is often seen in compounds like carbon tetrachloride (CCl4) or carbon dioxide (CO2), where carbon shares electrons with other elements to complete its octet.
The oxidation number of the nitrogen atom in the cyanide ion (CN-) is -3. This is because carbon is more electronegative than nitrogen, so it takes the -1 oxidation state while nitrogen takes the -3 oxidation state to balance the overall charge of the ion.
Assuming you mean what is the oxidation number of each atom in the compound C3H8O? Oxidation rules state the the sum of all oxidation numbers in a neutral molecule equals 0. 1. O = -2 2. H = +1 3. C = -2 These numbers are derived from... (-2) + (+1 x 8) + (-2 x 3) = 0
The sum of the oxidation numbers of all carbons in C6H5CHO is equal to 0. This is because the oxidation number of carbon is -2 in CH3CHO, and there are six carbons in C6H5CHO. So, 6 * (-2) = -12. However, since the overall charge of the molecule is 0, the sum of the oxidation numbers of all carbons must be 0 to balance the charge.
Phosphorus is in the p block. It shows +5 and +3 oxidation numbers.
