In Potassium Sulphate there are two atoms of potassium, one atom of sulphur and four atoms of oxygen so there are 7 atoms and three elements.
Potassium-1, Chlorine-1
Number of atoms altogether: 2.
There is 1 sulfur atom in potassium sulfate (K2SO4).
Potassium sulfide (K2S) has 3 atoms in the molecule.
Most likely, this is Potassium's (K) atomic number.
nitrogen
There are 19 protons in a potassium atom, ion, and isotope. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons.
The atomic number of potassium is 19 and the atomic weight is 39.0983 grams per mole. See the Web Links to the left for a periodic table where you can find the atomic number and atomic weight of all the elements!
The atomic number of potassium is 19. This means that potassium atoms have 19 protons in their nuclei. Neutral potassium atoms will also have 19 electrons. So then you follow the rules for the orbital filling pattern for the atoms of the elements, until you get to 19 electrons, and you get the following: 1s22s22p63s23p64s1.
"Atomic number" is an expression for chemical elements, not for compounds.
Potassium.
KNO3 has 3 elements which are potassium, Nitrogen and Oxygen.
Only elements have a particular (unique) atomic number. Potassium (K) has 19 and chlorine (Cl) has 17 as atomic number (= proton number)
Most likely, this is Potassium's (K) atomic number.
nitrogen
Because it contains all the atoms in the reactants and how they rearrange in the products. Sulphuric Acid and Potassium hydroxide reacted for the products potassium sulphate and water. This does not show the hydrogens, oxygens, potassium and sulphurs. It only hints at were the sulphur and postassium might be. Nor does it show the numbers of atoms of each element. Here is the reactant equation. H2SO4 + 2KOH = K2SO4 + 2H2O This shows the were the elements( hydrogen, oxygen , sulphur, and potassium) are. The number of each element and the molar ratios (the big number to the left of the compound). It also demonstrates the Law of Conservation of Mass, That all the reactant elements are still present in the products. It also indicates the arrangement and number of the elements in each substance.
Potassium is NOT a compound made of 2 elements,it is an elementby itself, exsisting of one kind of atoms: symbol K, group 1atomic number 19, mass 39.1 a.m.u.
It has 19. If you look at the periodic table of elements potassium (k)'s atomic number is 19. An atomic number Is how many protons is in it's nucleus. So the answer is 19
Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.
Sodium and potassium are the elements from group one in periodic table. They are the backbone elements in electrolyte balance in the body. Sodium ion remains in the extracellular compartment. Potassium remain in the intracellular compartment. Intracellular means inside the cells. You have approximately double the number of potassium ions in the body as compared to sodium ions.
