Explanation

According to the periodic trends, Nitrogen (N) has the largest ionization energy among the given atoms: N, P, As, and Sb. 

 Ionization energy generally increases from left to right across a period on the periodic table.

Since Nitrogen is to the left of Phosphorus, Arsenic, and Antimony, it will have the highest ionization energy.

Additionally, within a group, ionization energy decreases down the column. 

Explanation

The best choice to replace the word "disgust" in the sentence "The doctor grounded his teeth in disgust" is displeasure.

disgust نفرت

displeasure ناراضگی

Explanation

Cluster means اسی طرح کی چیزوں کا ایک گروپ قریب سے جمع ہوا

Bunch means ایک گروپڈ مجموعہ کی وضاحت کرنا

Explanation

F-block elements are also known as inner transition elements.

They include the lanthanides and actinides and are located at the bottom of the periodic table, separated into two rows.

This placement is due to their electron configuration, where the "n-2" f orbitals are being filled.

Explanation

The biosphere includes all of these: the Atmosphere, the Hydrosphere, and the Lithosphere.

The biosphere is the zone on Earth where life exists, encompassing the living organisms and their interactions with the surrounding environment, including the atmosphere, hydrosphere (water bodies), and lithosphere (land).

Explanation

Vacuum distillation is used to distill substances at lower temperatures by reducing the pressure, which lowers the boiling point of the substances.

Explanation

 In a p-n-p transistor, the collector current is slightly less than the emitter current.

This is because a small portion of the current flowing from the emitter to the base recombines with electrons in the base region, reducing the current that reaches the collector. 

Explanation

The comparative rates at which solutes move in paper chromatography depend on Rf values. 

Rf values (retention factors) represent the ratio of the distance traveled by a solute to the distance traveled by the solvent front on the paper.

Since different solutes have different polarities and affinities for the mobile and stationary phases, they will travel at different speeds, resulting in unique Rf values.

Therefore, the comparative movement of solutes is directly related to their Rf values.
