An atom loses two electrons. what is it referred to now?
a) a charged particle
b) a neutral atom
c) anion
d) cation

When an atom loses two electrons it is referred as Cation.

Explanation:

An atom contain equal number of both protons and electrons.When an atom loses 2 electrons it gets oxidized and acquires 2 unit positive charge.

 For example

        Ca-2e-=Ca2+

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
