What else can I help you with?
What atom has the same number of electrons as in ion of calcium?
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas Argon.
Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?
No, potassium hydroxide cannot be made by mixing potassium sulfate and calcium hydroxide. Potassium hydroxide is typically produced through the electrolysis of potassium chloride. Mixing potassium sulfate and calcium hydroxide would not result in the formation of potassium hydroxide.
What is the ratio of potassium atoms to nitrogen?
The chemical formula of potassium nitride is K3N. The ratio potassium atoms/nitrogen atoms is 3.
What atoms does calcium acetate have?
It has calcium, carbon, hydrogen and oxygen.
What is the number of atoms for potassium iodide?
There is one atom of potassium in a unit of potassium iodide.
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).
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 many atoms of calcium and potassium will there be after 4.12 and times 105 years?
The number of atoms of calcium and potassium after 4.12 × 10^5 years would remain the same, as these elements do not spontaneously change into other elements over such timescales. Assuming a stable environment and no external factors affecting the atoms, the number of calcium and potassium atoms would remain constant.
What characteristics do atoms of argon-40 potassium-40 and calcium 40 have in common?
They have the same mass.
What characteristics do atoms argon-40 potassium-40 and calcium-40 have in common?
Atoms argon-40, potassium-40, and calcium-40 all have 40 protons, but differ in the number of neutrons in their nuclei. They are all stable isotopes, with no natural radioactivity.
What characteristics do atoms of argon-40 potassium-40 and calcium-40 have in common?
Argon-40, potassium-40, and calcium-40 all have 40 protons and electrons in their atoms, but they have different numbers of neutrons. They are all stable isotopes, although potassium-40 is radioactive and undergoes decay to form argon-40.
How many atoms are present in Ca3P2?
Ca3 (PO4)2 has 13 atoms in the molecule.
Why is calcium harder than potassium?
Calcium is harder than potassium primarily due to its atomic structure and bonding characteristics. Calcium has a higher atomic number and a stronger metallic bond, which results from its higher charge density and greater number of valence electrons contributing to stronger interactions between atoms. In contrast, potassium has a larger atomic radius and weaker metallic bonds, making it softer and more malleable. Additionally, the presence of more closely packed atoms in calcium contributes to its increased hardness compared to potassium.
Is calcium or potassium an hallogen?
Calcium or Potassium are not halogens but metals.
What two atoms have 20 electrons combined?
Two atoms that have a total of 20 electrons combined could be calcium (Ca) and potassium (K), as calcium has 20 electrons and potassium has 19 electrons. Alternatively, you could have two atoms of calcium, which would also sum up to 20 electrons. Another combination could be a calcium atom (20 electrons) and an oxygen atom (8 electrons) if we consider a different arrangement, but that would exceed the total.
What atom has the same number of electrons as in ion of calcium?
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas Argon.
