An element in the halogen family with an electron configuration of 1s^22s^22p^63s^23p^5, contains valence electrons and has a common ionic charge of ?

A. 7, +1
B. 7, -1
C. 5, -3
D. 5, +5

B. 7,-1

Explanation:

The element stated above is Chlorine. Chlorine is in the halogen family, and all halogen family contains 7 valence electrons and -1 ionic charge.

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.
