The amount of energy required to remove an electron increases from left to right. This means that the atoms are able to hold on to their valence electrons more and more tightly. Thus, it gets harder to remove an electron as the atomic number increases.
Going down a group, the element doesn't change much. However, the size of the atom increases greatly, and because of this, so does the distance between the nucleus and the valence electrons. That decreases the magnitude of the force of attraction between the nucleus and the outermost electrons. Thus, IE decreases going down a group from top to bottom.

TaigaThe energy required to remove an electron from an atom (ionization energy) changes based on factors such as the atomic structure, number of electron shells, and the attraction between the electron and nucleus. As you move across a period in the Periodic Table, the ionization energy generally increases due to increased nuclear charge. As you move down a group, the ionization energy generally decreases due to increased distance from the nucleus.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. The electrons are not lost easily and hence a large amount of energy is required (high ionization energy) to remove an electron.

The energy required to remove an electron from a neutral atom is the atom's?
The energy required to remove an electron from a neutral atom is the atom's ionization energy. It represents the amount of energy needed to remove the most loosely bound electron from an atom in its gaseous state.
Define ionization energy of an element?
Ionization energy is the amount of energy required to remove one electron from a neutral atom in the gaseous state. It is a measure of how tightly the electron is held by the nucleus of the atom. Elements with higher ionization energies require more energy to remove an electron and are less likely to form ions.
What energy is required to remove an electron from an atom?
The energy needed to remove an electron from an atom (in the gaseous state) is called the IONIZATION ENERGY.
What is the energy required to overcome the attraction of protons in the nucleus and remove an electron from a gaseous atom?
The energy required to remove an electron from a gaseous atom is called the ionization energy. This energy depends on factors such as the atomic structure and the strength of the attraction between the nucleus and the electron. The higher the attraction, the higher the ionization energy needed to remove the electron.
What is the energy required to remove an electron from an atom in gaseous state called?
ionization energy
