Periodic Trends

In class we have been studying the periodic table and trends. The group is the vertical columns in the periodic table. The periods are the horizontal lines. The periodic table is organized by the atomic number. The electron affinity is how much the energy is released. The an electron is added on to the neutral and negative atom. The ionization energy is how much of the energy has been removed. It will be removed from the negative atom. The electronegativity is that it decreases as the atomic number gets bigger. It also increases the distance between the valence and nucleus.
