What type of bond will form between calcium (ca) and fluorine (f)

Ionic

Explanation:

Calcium is present in group two. It has two valance electrons. It loses its two electrons to get complete octet.

Fluorine is present in group seventeen. It has seven valance electrons. It needed just one electrons to complete the octet. That's why two fluorine atoms are bonded with one calcium atom.

When both react with each other ionic compound is formed between them because of large electronegativity difference. The electronegativity of fluorine is 3.98 and for calcium is 1. There is large difference is present. That's why electrons from calcium is transfer to the fluorine. Calcium becomes positive and fluorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations.

Ca + F₂  →   CaF₂

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.
