What is the main reason there is more variation between n, p, as, sb, and bi? they are in different periods there are varying classifications of material different number of valence electrons increased number of subshells going down group

increased number of subshells going down group

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
