Are the atoms of potassium larger than the atoms in calcium?

yes


Would calcium be more chemically similar to potassium or to magnesium?

Calcium is more chemically similar to magnesium than to potassium. Both calcium and magnesium are alkaline earth metals, while potassium is an alkali metal. This means that calcium and magnesium have similar chemical properties due to their position on the periodic table.


How does calcium atomic radius compare to magnesiums radius and potassium's radius?

Calcium has a larger atomic radius than magnesium because it is located further down in the periodic table, resulting in an increased number of electron shells. However, potassium, being in the same group as calcium but further down, has a larger atomic radius than both calcium and magnesium. Thus, the order of atomic radii from smallest to largest is magnesium, calcium, and then potassium.


Why boiling point of calcium is higher than that of potassium?

The boiling point of calcium is higher than that of potassium primarily due to the stronger metallic bonding in calcium. Calcium, being a divalent metal, has two valence electrons that contribute to stronger metallic bonds, while potassium, a monovalent metal, has only one. This results in a higher energy requirement to break the bonds in calcium, leading to a higher boiling point compared to potassium. Additionally, calcium's smaller atomic size and higher charge density further enhance its bonding strength.


Is calcium chloride and potassium chloride crystals in a beaker a pure substance?

Calcium chloride and potassium chloride are pure substances.

Which has more valence electrons potassium or calcium?

Calcium has more valence electrons than potassium. Potassium has only 1 valence electron, while calcium has 2 valence electrons.


Is the atomic radius of potassium larger than of calcium?

Yes, the atomic radius of potassium is larger than that of calcium. This is due to potassium having one more electron shell than calcium, leading to a larger atomic radius.


Is iron softer than potassium?

No, iron is harder than potassium. Iron is a metal with a higher Mohs hardness rating than potassium, which is a soft alkali metal.


Are the atoms of potassium larger than the atoms in calcium?

yes


Which element has a higher melting point potassium or calcium?

Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius


Is calcium or potassium an hallogen?

Calcium or Potassium are not halogens but metals.


What element has more protons than chlorine but fewer than potassium?

Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.


Does Cartilage harder than bone?

No. It does not have the amount of calcium as bone.


Which is greater the second ionization energy of potassium or that of calcium?

The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.


Would calcium be more chemically similar to potassium or to magnesium?

Calcium is more chemically similar to magnesium than to potassium. Both calcium and magnesium are alkaline earth metals, while potassium is an alkali metal. This means that calcium and magnesium have similar chemical properties due to their position on the periodic table.


Why is the melting point of calcium higher than the melting point of potassium?

Every element is different. The atomic number of potassium is 19 and calcium's is 20. Potassium's atomic mass is 39.098 and calcium is 40.08. these two elements are very different. Potassium being an Alkaline Metal while calcium is an Alkaline Earth Metal. You might be thinking. Oh my goodness those are like the same thing, but actually they are very different. Potassium just happens to less dense than calcium.


Which has more atoms calcium hydroxide or potassium phosphate?

Potassium phosphate (K3PO4) has more atoms than calcium hydroxide (Ca(OH)2). This is because the formula for potassium phosphate contains 4 atoms (3 potassium atoms and 1 phosphorus atom), while the formula for calcium hydroxide contains 3 atoms (1 calcium atom and 2 hydrogen atoms).
