Re: ionization energy
Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It generally increases across a period (from left to right) in the periodic table due to increasing nuclear charge, making it more difficult to remove electrons. Ionization energy decreases down a group (from top to bottom) because electrons are in higher energy levels, farther from the nucleus, and experience weaker attractive forces.

Re: ionization energy
Ionization energy is a measure of how easy it is to make that element an ion, meaning that it measures an atom's tendency to give up electrons. High ionization energy means that an atom will not easily give up an electron, and vice versa. Ionization typically increases across a period and up a group. It follows a very similar trend to that of electronegativity. Hope that helps!

Re: ionization energy
Ionization energy is the energy needed to remove an electron from an atom, making the atom positively charged. The trend on the table for the first ionization energy is increase from left to right and it decreases down the group.
Second ionization energy is the energy required to remove a second electron from an ion that already lost an electron. The trend for second ionization energy follows the trend of increasing energy across a period and decreasing down (but downward, it is not as consistent as the first group)
Second ionization energy is the energy required to remove a second electron from an ion that already lost an electron. The trend for second ionization energy follows the trend of increasing energy across a period and decreasing down (but downward, it is not as consistent as the first group)
