Final answer:
In group 14 of the periodic table, carbon (C) has the highest electronegativity with a value of approximately 2.55.
Step-by-step explanation:
The group 14 element with the largest electronegativity is carbon (C). Electronegativity is the tendency of atoms to attract electrons, with values ranging from about 0.7 for francium (Fr) to 4.0 for fluorine (F). Group 14, found in the p-block of the periodic table, consists of carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). As electronegativity generally increases across a period and within group 14, carbon has the highest electronegativity value of approximately 2.55, according to Linus Pauling's scale.
