Which atom gives up its electrons most easily?<br><br> THE ANSWER IS “Rb”
Sedbober [7]

Answer:

cesium

In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron

Separation technique used to separate mud and water without heating​
Murrr4er [49]

Answer:

Separation technique used to separate mud and water without heating​:

<u>Sedimentation-Decantation</u>

<u></u>

Explanation:

<em>1.The settling of the heavier particle at the bottom when the container is left undisturbed is called </em><u><em>sedimentation.</em></u>

<u><em></em></u>

<u><em>In a mixture of Mud and water :</em></u>

In this process the heavy mud particles settle at the bottom due to their high density .

2. Decantation : It is the process of pouring out the upper clear layer of the light particles.

<u><em>In a mixture of Mud and water :</em></u>

The water is lighter and form a clear layer over the settled mud particles. Hence by decantation the clear water is poured into a clean separate container

Thus mud remain in the bottom and the mixture is separated
