<em>
Cation</em>
When naming a chemical compound, <u>the cation</u> is written first before anything else.
A typical ionic compound consists of two components - the cation and the anion. While the <u>cation is positively charged in ion</u>, <u>the anion is negatively charged. </u>The cation of a typical ionic compound is named first before the anion and the name often carries that of the element that composes it.
The name of the element that makes up the anion is modified by removing the last few characters ending the name and replacing it with the suffix 'ide'. For example, NaCl is named sodium chloride.
Answer:
It represents the <em>number of atoms</em> of that particular element present in the compound. In C₂H₄O₂ there are 2 Carbon atoms, 4 Hydrogen atoms and 2 Oxygen atoms.

I'd guess A or D, but my gut says A
Answer is: Li < Na < K.
Lithium (Li), sodium (Na) and potassium (K) are alkaline metals.
Alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons (one electron).
Potassium has lowest ionization energy and it is most reactive, because valcense electrons is farthest from nucleus.
Electron configuration of lithium atom: ₃Li 1s² 2s¹.
Electron configuration of sodium atom: ₁₁Na 1s² 2s² 2p⁶ 3s¹.
Electron configuration of potassium is: ₁₉K 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹.
The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
