What is the valency of a Carbon atom?

Question

is electro-positive or
electro-negative?

Answer 1

Its usually +4.

Think CO2, O is always -2 which means 2 x -2 = -4, so the C needs to be +4 to balance the -4. But you can also have CO, where the C is +2, and rarely +3.

Now the second part of your question asks about electropositive vs electronegative, which is not the same as valence. Carbon is a non-metal and very slightly electronegative. It forms covalent bonds but can not acquire sufficient electrons to form negative ions.

Hope that helps!

Valence does not have a + or a -. That is the charge or oxidation state. So Cl and Na would both have a valence of 1. Hence Carbon has a valence of 4.

Answer 5

4

Answer 6

Carbon has 4 valency and carbon is electronegative with Electronegativity2.55 (Pauling scale)

Answer 7

In co2(carbondioxide), valency of carbon is 4. In co(carbo mono oxide) valency of carbon is 2

Answer 9

Valency of carbon depends on what type of compound you are talking about. If you are talking for Inorganic salts, Carbon is present usually as carbonate or bicarbonate. Here it is +4 valances. For Carbides (Calcium carbide CaC2it is -1), it depends on metal atom.
For Organic compounds it is forming covalent bond and idea of valency is not as valid as for inorganic compounds, because here electron partnership is attaching one atom with other atoms, it is not giving and accepting of electrons.

Answer 10

valency of carbon atom is 4.carbon is usually electronegative. it mostly forms covalent bonds with its four valence electrons
