Answer 1

Answer:

Explanation:

the measure of the tendency of an atom in a covalent bond to attract a bonding pair of electrons is called Electronegativity(X).

a) Ca<Al<O    (metals have less electronegativity)

b) Cl>Cu>K     (Chlorine is the second-highest electronegative atom)

Answer 2

Answer:

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

(a) Ca,Al O

(b) Cl>Cu>K
