Hey There!_____________________________________

$\huge\boxed{Option C}$

_____________________________________IONIC BOND:

Ionic bond is a type of bond which is formed between metals and non-metals. The group which provide the Metal are IA and IIA i.e. S block elements. The group which mostly provide non-metal is VII A i.e. halogens. The Metals give up their ONLY Valance shell electron which is accepted by the Non-metal. This results in formation of ions, The Metals gets the positive charge thus called cation and The non-metal gets a negative charge thus called anion. These Positive and Negative ion attract each other resulting in the formation of IONIC BOND.

The Ionic bond is formed between The metal and non metal because, the metals have low ionization energy due to which the valence shell is ejected out easily, and The Non-Metals have high electron affinity which means that they attract an electron with greater force because they need one electron to complete their octet.

_____________________________________Question:

Question has given two atoms Potassium and chlorine. Potassium(Group 1) is metal, Chlorine(Group 7) is non metal. As you can se that there is only one electron in the outer shell of Potassium "K" and Chlorine need only one electron to complete its outer shell so Potassium will give its electron to Chlorine. Due to this reason K will become positive and Cl will become negative and they will both attract eachother forming ionic bond.

So the answer is Option C: Electron will be transferred from the potassium to the chlorine atom.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

Answer from: Quest

the formula for the conversion of temperature from degree celsius to kelvin is:

$k = ^{o}c + 273.15$

the sample of water at $38^{o}c$ is converted to kelvin temperature by using the above formula as:

$k = 38^{o}c + 273.15 = 311.15 k$

on comparing the two samples of water at $38^{o}c$ or we can say that at $311.15 k$ and at $295 k$ respectively. the difference between the temperatures of two samples of water is:

$311.15 k - 295 k = 16.15 k$

hence, one can say that the sample of water at $38^{o}c$ is greater than the sample of water at $295 k$ by $16.15 k$ .
