when carbon is not in exited state it has two valency to form the bond.
But when it is exited it has four unpaired of electrons.
So therefore carbon has a four valency and can form four bonds.
valency of carbon is positive as it gives it electron so it is positively charge
A valance electron is one that is associated with an atom. The valence orbit is the one that electron travels in.
In fact an electron has no valency, though it is equal to a -1 (minus one) charged anion like Cl-, having a valency of -1
The combining power of carbon is 4. This means that each carbon atom can form 4 bonds.
The valency of hydrogen is +1 because it has a tendency to lose an electron while combining with an Elelment. This gives it a positive valency.
Valency of carbon is 4. It remains 4 in ethane too.
The valency of lithium is 1. It has one valence electron in its outer shell.
The valency of iodide is -1. This means that iodide typically gains one electron to achieve a stable electron configuration in chemical reactions.
In methane (CH4), the valency of carbon is 4. In carbon dioxide (CO2), the valency of carbon is 4 as well. Carbon has four valence electrons and forms four covalent bonds in both compounds.
The valency of sodium is +1
Valency of carbon is 4. It remains 4 in ethane too.
Carbon has a valency of 4, while sulfur has a valency of 6.
