The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest ionization energy.
it increases. the nuclear charge also increases
Within a group, first ionization energy generally decreases as you move down the group due to increasing atomic size and shielding effects. Across a period, first ionization energy generally increases due to increasing nuclear charge and effective nuclear charge. For example, within Group 2 (alkaline earth metals), the first ionization energy decreases as you move down the group from Be to Ra. Across Period 3, the first ionization energy increases from Na to Cl.
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
The trend in period 2 ionization energy across the elements increases from left to right.
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
Across a row on the periodic table ionization energy increases. Down a column, ionization energy decreases. --------------------------------------------------------- The first Ionization energy of Boron is 800.6 kJ mol-1
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
Ionization energy increases as you go across a period, but as you go down a group it decreases.
The ionization energy increases across a period because as you move from left to right, the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons. This makes it harder to remove an electron, resulting in higher ionization energy.
The first ionization energy tends to increase across a period from left to right on the periodic table. This is due to the increasing nuclear charge and decreasing atomic radius, which leads to a stronger attraction between the electrons and the nucleus.
