I have to also state the atomic radius trends on the periodic table.

look in your book its not that hard

"Atomic radius" is a measurement of how big an atom is. If you think of the atom as a ball, the radius is just that - half the diameter of the ball.
Talk about trends in atomic radius as you go down a family and across a period (do the atoms tend to get bigger or smaller and why) The most interesting part will be why the atoms tend to get smaller as you go across the table.
Then talk about what happens to the radius when the atom loses electrons and what happens to the radius when the atom gains electrons. Then do the "down a family" and "across a row" thing again.
If you need to get really technical you can go into why the transition elements don't seem to have much of a trend; ask your professor how far you should go and how much time you have for your presentation. You should be able to find all the information you need in a good chemistry text book.

You should definetly include the trend in atomic radius and you go down the periodic table, right to left and top to bottom. Also, include what happens to an atom's radius when it forms an anion or cation.

I don't have an oral presentation on atomic radius. You'd probably better start researching it.

atomic radii I think decreases left to right and increases top to bottom.

start reading a book or ask your professor / instructor about what you should have been paying attention to all semester
