Explain how to arrange the following in increasing order of atomic size/radius: Al, C, Si

C, Si, Al

Explanation:

We use periodic trends to help us find the atomic radii. The trend for atomic radii on the Periodic Table of Elements is down and to the left. So whichever elements are furthest to the left and farthest down have the largest atomic radii.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
