Copper has an atomic number of 29 that means there are 29 protons in the nucleas of each copper atom that's waht the atomic number the number of protons in an atom in the atom of a ceartain element if one copper atom contains 29 protonshow many electron are in 4 atoms of copper

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 .
