Except for elements with atomic number 1 and 2, all other elements are stable with how many electrons in their outermost energy level

Except for element   with element with atomic number 1 and 2 all  other elements are stable with  8 electron in their outermost energy level.

explanation

stable element has eight electron in their outermost  energy level. for example neon which has    2.8 electronic configuration is stable since has eight(8) electrons in its outermost energy level.

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.
