Why does ionization energy tend to increase as you move across a period?
As you move across a period, you add a proton in the nucleus and an electron in the outer shell. Ther greater number of protons causes a stronger pull on the electrons. The electrons are held tighter, basically, so the energy you have to put in to break one off increases.
