Electronegativities of the elements na, al, p, and cl follow a specific trend across the period. based on this trend, an electron will be most strongly attracted to a) na / b) al/ c) p/ d) cl.

Electronegativity is the ability or tendency of an atom to be attracted to an electron. This trend in the periodic table is that it increases from left to right and it increases from bottom to top. Halogens have highest electronegativity. The correct answer is D. Chlorine. The rule states that in almost full octet shell, just like in halogens, it is easier to get an electron than donate one.

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.
