Question

what is electronegativity?
the size of the atom from the nucleus to the edge of the electron cloud
the distribution of electrons around a single atom
the likelihood of an atom to gain an electron from another atom during bonding
the likelihood of an atom to lose an electron

Explanation:

Electronegativity is the ability of an atom in a chemical bond to attract electrons from another atom. Among the options, the likelihood of an atom to gain an electron from another atom during bonding best describes it.

Answer:

the likelihood of an atom to gain an electron from another atom during bonding
