Potassium and calcium are both in period 4 of the Periodic Table because they both have 4 electrons in their outermost energy level. This means they both have the same number of protons and the same number of electrons, which puts them in the same period. Additionally, they both have the same number of shells, which is why they are both in period 4.

Which is strong electrolyte potassium chloride or calcium chloride?
Both potassium chloride and calcium chloride are strong electrolytes when dissolved in water or when molten.
Which is a hallogen poatssium or calcium?
Neither Potassium nor Calcium is a halogen since both are metals.
How are potassium and calcium atoms similar?
There near eachother on the periodic table
What element can be doing in the same period as the element potassium?
sodium and lithium are both group 1 elements (like potassium)
Are Potassium and Calcium in the same family in the periodic table of elements?
Yes. They are because they are both are in the same group and are metals.
Is it period or implantation bleeding?
i think both, period... wait.. i dont need to explain
What is the chemical formula potassium and bromine?
Groups go in columns (up and down) and periods go in rows (left to right). Potassium is on the same row as bromine, therefore they are in the same period.
Potassium has four energy level how many energy levels do you predict calcium iron nickel ans zinc will have?
both have 4 energetic levels
Will potassium share more properties with calcium or sodium?
potassiumwill share more properties with sodium because both are Alkali metals and have same number of valence electrons.
Which of the bases of sodium hydroxide calcium hydroxide potassium hydroxide magnesium hydroxide and ammonium hydroxide are alkalies?
Both KOH and NaOH are strong bases. Calcium hydroxide is not nearly so strong and NH4OH is a fairly weak base.
Reason why calcium hydroxide is used to detect carbon iv oxide while potassium hydroxide solution is not?
Both hydroxides will react with carbon dioxide to form their respective carbonates. Calcium carbonate is largely insoluble in water and so it will form a visible solid precipitate. Potassium carbonate is soluble in water, so there will be no visible change to the solution.
Is oxygen in both lime and lye?
Yes, Lime is CaO (calcium oxide) and lye is NaOH or KOH (sodium or potassium hydroxide). In the above formulas O represents oxygen.
