Question

what is carbon affinity​

Answer 1

Answer:

Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.

Answer 2

Answer:

The electron affinity of the carbon atom is estimated to be 2.2 e.v. from linear extrapolation of the ionization potentials of the isoelectronic sequence C−, N, O+, F++, and Ne+++. Experimentally it is shown that a carbon filament above 1850°K. gives off negative ions under proper conditions.
