What happens in the nucleus when a lithium atom becomes an ion

An atom that gains a negative electron, it becomes a negative ion. ... A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge.

This means a Lithium atom formed into a Lithium ion by losing one of its electrons. It has three electrons and three protons to begin with. So when it loses or gains one the amount isnt equal, that is why it becomes an ion. If it gained electrons it would have a negative charge on the nulcleus, though if it lost electrons it would have a positivec charge. Hope this helped!!

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 .
