(a)
Interpretation:Element having larger ionization is to be identified.
Concept introduction:
The first ionization energy is the energy required to extractthe outermost electron from an isolated neutral atom. Ionization energy depends on the size of the atom and the electronic configuration of the element.
(a)
Answer to Problem 25LC
Sodium
Explanation of Solution
The first ionization energy and atomic size are inversely related. The larger the size,the less will be the first ionization energy. Down the group atomic size increases. Sodium and potassium are present in the same group but in different periods. Potassium is present below sodium in the periodic table, so its atomic size is larger than the atomic size of sodium. Thus, the first ionization energy of sodium is more.

Answer to Problem 25LC
Phosphorous
Explanation of Solution
The first ionization energy and atomic size are inversely related. The larger the size less will be the first ionization energy. Phosphorous and magnesium are present in the same period and across the period atomic size decreases. Phosphorous is present right to magnesium, so its atomic size is less than the atomic size of magnesium. Also phosphorous is having half filled outermost shell which makes it more stable. Thus, the first ionization energy of phosphorous is more than that of Mg.

- The acid-base indicator HX undergoes the following reaction in a dilute aqueous solution: HX (color 1) H+ + X- (color 2). The following absorbance data were obtained for a 0.00035 M solution of HX in 0.1 M NaOH and 0.1 M HCI. Measurements were made at wavelengths of 450 nm and 620 nm using a 1.0 cm glass cuvette. 450 620 A(460 nm) A(630 nm) 0.1 M NaOH 0.1 M HCI 0.065 0.435 0.895 0.150 In the 0.1M NaOH solution, the indicator will be almost 100% in the X- form, while in 0.1M HCI, the indicator will be nearly 100% protonated (HX). Calculate the acid dissociation constant for the indicator if a pH=5 buffer solution containing a very small amount of indicator exhibits an absorbance of 0.567 at 450 nm and 0.395 at 620 nm (measured in a 1 cm glass cuvette).arrow_forwardShow work...give the name of the given compound.
