Question

Check out the picture of the periodic table of elements. Follow the arrow from left to right. What is an important trend you would notice about the elements as you move from left to right?
A) The elements change from gases to solids.
B) The elements change from solids to liquids.
C) The elements change from metals to nonmetals.
D) The elements change from not very reactive to very reactive.

Answer 1

Answer:

C) The elements change from metals to nonmetals.

Reason:    As we move from left to right, as atomic radii decreases, the effective nuclear charge decreases and hence the electronegativity increases. Electronegativity leads to nonmetallic behaviour(extreme right) and electropositivity leads to metallic behaviour(extreme left)
