What is the usual charge on an ion formed from an atom that originally had five valence electrons? a. 0 b. 3 c. -3 d. 5

c) -3

Explanation: The charge on an ion equals to the number of electrons an atom  gain or lose to get its nearest noble gas like electron configuration.

If an atom has 5 valence electrons then it would accept three electrons to complete 8 valence electrons in its valence shell.

8-5 = 3

Since, the atom has to accept 3 electrons, the usual charge on an ion formed will be -3.

(The charge is negative if the electrons are accepted and its positive if the electrons are lost.)

So, the correct choice is c) -3.

For example, N has 5 valence electrons, the usual charge on its ion is -3 as it accepts three electrons to complete its octet.(Neon like electron configuration).

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.
