Answer:
As potassium is larger than sodium, potassium's valence electron is at a greater distance from the attractive nucleus and is so removed more easily than sodium's valence electron. As it is removed more easily, it requires less energy, and can be said to be more reactive.

Answer:
1.7x10²³ Fluorine atoms are present
Explanation:
To solve this question we must know that, to find the amount of atoms of a substance from its mass, we have, as first, to convert this mass to moles using molar mass of the substance. With the moles we can find the amount of molecules using Avogadro's number. And with the formula we can know the atoms presents:
<em>Moles Fluorine (F₂, Molar mass: 37.997g/mol)</em>
5.3g * (1mol / 37.997g) = 0.139 moles F₂
<em>Molecules F₂:</em>
0.139 moles F₂ * (6.022x10²³molecules / mol) = 8.4x10²² molecules F₂
As 1 molecule of F₂ contains 2 atoms of Fluorine:
8.4x10²² molecules F₂ * 2 =
<h3>1.7x10²³ Fluorine atoms are present</h3>
