Gerry is looking at an unknown element. He knows it has 1 valence electron and is highly reactive with water. What group is the element most likely in? Group 1
Group 2
Group 17
Group 18

Group 1

because they have just one valance electron, group 1 elements are very reactiv.

the answer would be c

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 .
