3 chemistry questions? really need help! i would really appreciate it. =]?

1. Explain how elements are arranged on the periodic table. What does the table tell you when you read it like the sentences in a book are read: left to right and top to bottom?

2. How is it possible that, when adding protons while moving across a period, the size of the atom actually shrinks? Why is the same trend not true as you moce down a group? Give at least one example to support your answer.

3. Why would an atom with a high electronegativity be a great match for an atom with low ionization energy?
