There is an increase in the frequency of particle collisions which leads to the increased rate of the reaction.

Explanation:

Hydrochloric acid reacts faster with the powdered zinc than with the equal mass of zinc strips.

Since the surface area of the Zinc particle increases when it is powdered and has more active spots when compared to less number of active sites in Zinc strips and so the number of collision between the Zinc particles and the particles of Hydrochloric acid also increases and consequently the rate of the reaction also enhances.

So there is an increase in the frequency of particle collisions.

The atoms of which element will typically form ions

Musya8 [376]

Ions are electrically charged particles, meaning, that whenever any type of atom loses or gains electrons it is forming a new type of structure, or ion.

Metal atoms form postive ions, Non-Metals form negative ions.

The strongest type of bond that can occur between two ions, when they are oppositely charged, are Ionic Bonds. The most commonly known ionic bond is seen in Sodium and Chlorine, which when combined give us NaCl or Sodium Chlorine, aka Salt.

+1 charge = Group 1, Metals

+2 charge = Group 2, Alkali Metals

-1 charge = Group 17, Halogens

Provided is a periodic table marked with the charges for each group.
