What is the valency of a Carbon atom?

is electro-positive or
electro-negative?

Answer:
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!
Carbon is electronegative.
valancy - 4
Growth of filamentous carbon from lithium and cesium bromide doped Ni/SiO2 catalysts . the presence of both electropositive and electronegative adatoms.
Carbon has 4 valency and carbon is electronegative with Electronegativity2.55 (Pauling scale)
valency of carbon atom is 4.carbon is usually electronegative. it mostly forms covalent bonds with its four valence electrons
4 and it's it depends upon the type of bond formation
Valency- C++++

it is electo negative
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.
