Why is the first ionization energy of arsenic is greater than the first ionization energy of germanium because?
There's two ways to answer this question.
First electron configurations with half-filled sublevels are more stable then electron configurations that don't have half-filled sublevels. Since Selenium is one elctron away from achieving a more stable half-filled sublevel configuration it more readily gives up it's outermost electron, so less energy is requires to remove the outermost electron. Arsenic already has the stable configuration of half-filled sublevel so it wouldn't give up it's electron as readily, so more energy is required to remove it.
Another way to look at it is that Selenium's outermost electron is in a p orbital that already has an electron so there is electron electron repulsion present in that orbital so it's attraction to the nucleus is less which is why less energy is required to remove it so the ionization energy is less. Arsenic has it's outermost electron unpaired in the p orbital so there is no electron electron repulsion present in that orbital so more energy is required to remove it then for Selenium's outer most electron.
Hope this helps!

Why does germanium has greater first ionisation energy than gallium?
Germanium has a greater first ionization energy than gallium because germanium has a smaller atomic size and thus a stronger nuclear charge, making it more difficult to remove an electron. Additionally, the electronic configuration of germanium (4d^10 5s^2 5p^2) is more stable compared to gallium (4d^10 5s^2 5p^1), resulting in a higher ionization energy.
Why arsenic has larger ionization potential than cesium?
Arsenic has a larger ionization potential than cesium because arsenic's valence electrons are more tightly held due to greater effective nuclear charge and smaller atomic size, making it harder to remove an electron. In contrast, cesium has lower effective nuclear charge and larger atomic size, making it easier to remove an electron, resulting in a lower ionization potential.
Who has greater electronegativity bromine or arsenic?
Bromine, its as simple as its more to the RHS of the periodic table
Why is the first ionization energy of krypton greater than selenium?
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.
What are the different types of arsenic?
The two main types of arsenic are inorganic arsenic, which is often found in contaminated water and soil, and organic arsenic, which is commonly found in seafood. Inorganic arsenic is considered more toxic and a greater health concern than organic arsenic.
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.

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.
Why germanium shows good reducing properties?
because its size is big and hence have greater tendency to accept electrons.

Which element has the highest ionization rate Sodium aluminum calcium or phosphorus?
phosphorous has highest ionization enthalpy because along the period ionization will increase.
Why the ionization potential of nitrogen is greater than that of oxygen?
The ionization potential of nitrogen is greater than that of oxygen because nitrogen has a smaller atomic size and a higher effective nuclear charge compared to oxygen. This makes it more difficult to remove an electron from a nitrogen atom, requiring more energy.
Will germanium sink or float in water?
Germanium has a density of about 5.32 g/cm³, which is significantly greater than the density of water (approximately 1 g/cm³). Therefore, germanium will sink when placed in water.
