False. They don't borrow electrons at all. They already have their respective electron affinities. This is called as electronegativity, and it's an occurence where it already has its own from its actual structure. It never borrows any electrons at all.

<span>The slim exit of the
column is first persisted with glass wool or a permeable plate in order to sustain
the column packing element and keep it from getting out of the tube. Then the
adsorbent solid, which is usually a silica, is firmly packed into the glass
tube to make the separating column. The packing of the non-moving phase into
the glass column must be done with precaution to create an even distribution of
material. An even distribution of adsorbent material is very important to lessen
the existence of air bubbles and/or channels inside the column. To finish
preparing the column, the solvent to be used as the mobile phase is delivered
through the dry column. Then the column is said to be "wetted" and
the column must stay wet throughout the entire procedure. Once the column is properly
prepared, the sample to be separated is placed at the top of the wet column.</span>
Answer:
A. 2
Explanation:
A particle of water is made up of two hydrogen atoms and one oxygen atom. However, the question asked for how many types of atoms there are, so the answer is 2.
