The one created by mandeleev is not in order of increasing the atomic number
Delta energy on labelled diagram is attached below
Answer:

Explanation:
We are given the compound: Cs₃PO₄
According to the formula, 1 mole of cesium phosphate contains 3 moles of cesium, 1 mole of phosphate, and 4 moles of oxygen.
Therefore, there are 3 moles of cesium for 1 mole of cesium phosphate.

We want to calculate the moles of cesium in 3 moles of cesium phosphate, so we multiply the ratio by 3.


3 moles of cesium phosphate contains <u>9 moles of cesium.</u>
Image result for What happens to sodium chloride when it dissolves in water
Explanation: On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms
