The ion 27al3+ contains which combination of protons, neutrons, and electrons?

This ion has 13 protons, 14 neutrons and 10 electrons.

Explanation:

An ion is formed when an atom looses or gains electron.

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Atomic mass is defined as the sum of number of protons and neutrons that are present in an atom.

Atomic mass = Number of protons + Number of neutrons

For the given representation of ion, which is:  

We are given:

Atomic number = Number of protons = 13

Number of electrons = Number of protons - charge = 13 - (+3) = 10

Mass number = 27

Number of neutrons = Atomic number - Mass number = 27 - 13 = 14

Hence, this ion has 13 protons, 14 neutrons and 10 electrons.

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.
