krypton because it is an inert/noble gas, which means it has a complete outer shell and takes a lot of energy to remove an electron.
Neon
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
Argon (#18). It's a noble gas, which means it doesn't react, which means it will be really hard to get it to lose an electron.
The element in the fourth period with atoms that have the same number of electrons in their highest energy level as tin is germanium. Both tin and germanium are in the same group (Group 14) of the periodic table, so they have the same number of valence electrons.
Nitrogen deviates from the trend in ionization energy across period 2. It has a higher ionization energy than oxygen, which would be expected based on the trend of increasing ionization energy from left to right in a period. This anomaly is due to the half-filled electron configuration of nitrogen's outer energy level, making it more stable.

The element with the largest ionization energy in its period is typically found in the top right corner of the periodic table. This is because elements in this region have the highest effective nuclear charge, making it harder to remove an electron. In general, elements like helium, neon, and fluorine tend to have the highest ionization energies in their respective periods.
Neon
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.

The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
Ionisation energy differs between elements due to variations in the number of protons in their nucleus, which affects the strength of the attraction between the electrons and the nucleus. Elements with higher atomic numbers typically have higher ionisation energies due to increased nuclear charge. Additionally, ionisation energy generally increases across a period and decreases down a group on the periodic table.
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
