Chlorine (Cl) has the largest first ionization energy among the elements listed (Sb, Se, Cl, and Pb). Ionization energy tends to increase across a period and decrease down a group in the Periodic Table. Since Cl is located in the second period and is further right compared to the others, it has a higher ionization energy than antimony (Sb), selenium (Se), and lead (Pb).
No, helium does not have the largest first ionization energy of all the elements. Helium actually has the highest first ionization energy of any element, due to its small atomic size and stable electron configuration.
Helium has the highest ionization energy.
As an example potassium has a lower first ionization energy than aluminum (Al).
Helium has the highest ionization energy.
Barium has more energy levels. So it has lesser ionization energy.
Helium has the highest ionization energy.
Fluorine has the largest first ionization energy among the halogens.
The element with the largest first ionization energy is (a) Sb (antimony). It has the highest first ionization energy among the elements listed.
No, helium does not have the largest first ionization energy of all the elements. Helium actually has the highest first ionization energy of any element, due to its small atomic size and stable electron configuration.
Oxygen
The element with the highest first ionization energy in group 14 is carbon.
Fluorine has the largest first ionization energy among the halogens.
Element P (phosphorus) has a lower first ionization energy than element S (sulfur).
The first ionization energy of an element, like sulfur (s), is important in determining its reactivity. A low first ionization energy means it is easier for the element to lose an electron and form a positive ion, making it more reactive. Conversely, a high first ionization energy means it is harder for the element to lose an electron, making it less reactive.
Helium has the highest ionization energy.
Sodium (Na) has the lowest first ionization energy in period 3.
As an example potassium has a lower first ionization energy than aluminum (Al).
