The first ionization energy of krypton is greater than that of selenium because krypton is a noble gas with a full valence shell, making it more stable and harder to remove an electron from compared to selenium, which is a nonmetal and has an incomplete valence shell. This results in a higher ionization energy for krypton.

Why first ionization energy of krypton is greater than that of selenium?
The first ionization energy of krypton is greater than that of selenium because krypton has a stronger nuclear charge due to its higher atomic number, leading to a stronger attraction between the nucleus and the outermost electron. This makes it harder to remove an electron from krypton compared to selenium, which has a lower nuclear charge and an electron in a higher energy level, making it easier to remove.
What is krypton's ionization energy?
The ionization energy of krypton is 13.99 electronvolts. This is the energy required to remove an electron from a neutral krypton atom to form a positively charged ion.
Which has the larger sixth ionization energy Se or Br?
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom, etc. Ionization energy generally increases for every electron that is removed, and increases from left to right in the periodic table or if moving up the periods. In this case, from the periodic table (or according to Mastering Chemistry) Bromine (Br) has a larger sixth ionization energy than Selenium (Se).
What does the ionization energy tell you about an element?
Ionization energy is the energy required to remove an electron from an atom. It can provide information about an element's reactivity and ability to form ions. Lower ionization energy indicates easier removal of electrons and greater reactivity, while higher ionization energy means more energy is needed to remove electrons, indicating lower reactivity.
Why is the ionization energy of br lower than that of cl but higher than that of se?
The ionization energy of an element is influenced by its atomic structure and the ease with which electrons can be removed. Bromine (Br) has a higher ionization energy than chlorine (Cl) because it is located further away from the nucleus, resulting in less shielding and higher attraction for its outermost electron. Selenium (Se) has a lower ionization energy than bromine because it is in a higher energy level, making its outermost electron easier to remove.

Does selenium have a low first ionization?
Selenium has a moderate first ionization energy, with a value of 941 kJ/mol. This means that it requires some energy to remove the outermost electron from a selenium atom.
Does the element Br have the highest ionization energy?
Krypton has a higher value.
How does the ionization energy of Ne compare to that of Se?
Neon is a much smaller atom than selenium because neon has fewer occupied energy levels so it has a considerably smaller atomic radius. For that reason, it will be more difficult to remove an electron from Ne than Se, so Ne has the greater ionization energy.
Which has the larger sixth ionization energy Se or Br?
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom, etc. Ionization energy generally increases for every electron that is removed, and increases from left to right in the periodic table or if moving up the periods. In this case, from the periodic table (or according to Mastering Chemistry) Bromine (Br) has a larger sixth ionization energy than Selenium (Se).
Do krypton atoms become ions easily or no?
No, it is a noble element, therefore it has very high ionization energy.
Which is greater the second ionization energy of potassium or that of calcium?
The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.
Which has a greater ionization energy beryllium or germanium?
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
Why does bromine have a higher ionization energy than selenium?
Bromine has a higher ionization energy than selenium because bromine has a smaller atomic radius and stronger nuclear charge, making it more difficult to remove an electron from the outer shell. Additionally, bromine's electron configuration (4s2 3d10 4p5) is more stable compared to selenium's (4s2 3d10 4p4), making it require more energy to remove an electron from bromine.
What do we mean by the first second third ionization energies for a particular atom?
First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.
How ionization energy can be explained by bohr's atomic model?
In Bohr's atomic model, electrons orbit the nucleus in specific energy levels. Ionization energy is the energy required to remove an electron from an atom. Electrons in higher energy levels have greater ionization energy because they are held more tightly by the nucleus.
