Pottasium is a metal element. Atomic mass of it is 39.09.
The K comes from the Latin name for potassium, "kalium".
The atomic number is the same for the all isotopes of a chemical element.
The element krypton's atomic radius is 189 pm. This is a measurement of its atom sizes or the distance between the electron cloud and the nucleus.
Well... I think its Magnesium Sulphur CozMg-MagnesiumS-SulphurSo I Just Added the Both Together!
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.

Calcium's atomice weight is 40.078 amu (atomic mass units).
Pottasium is a metal element. Atomic mass of it is 39.09.
The atomic radius of calcium is about 197 picometers (pm).
Calcium is a metal element. Atomic mass of it is 40.
It means that 2 is calciums' mass number and atomic number
Potassium has a larger atomic radius compared to sodium. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of more energy levels. In the case of potassium and sodium, potassium is located below sodium in the same group, resulting in a larger atomic radius for potassium.
Calcium (Ca) has the atomic number 20, this means it has 20 protons and 20 electrons.
The gas, neon, is elemental and thus contains no calcium. Neon contains only neon. Note atomic number 10.
It is comparable to it.
Argon, with an atomic number of 18, comes before potassium, which has an atomic number of 19, because elements on the periodic table are arranged in order of increasing atomic number. This ordering is based on the number of protons in the nucleus of each atom.
