because potassium contains 19 protons
Pottasium is a meta element. Atomic number of it is 19.
Only elements have a particular (unique) atomic number. Potassium (K) has 19 and chlorine (Cl) has 17 as atomic number (= proton number)
The atomic weight of K (Potassium) is 39.0983 g/mol
The atomic number indicates the number of protons (19) and electrons (19).
Pottasium is a meta element. Atomic number of it is 19.
Potassium is highly reactive element. Mass number of K is 39.
Fluorine is a non metal element. Atomic mass number of it is 19.
The atomic number of potassium (K) is 19.The atomic weight of K is 30.0983 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!I believe the atomic weight is 39.0983.19
Potassium is a non metal element. Atomic number of it is 39.
Since the atomic number of an element corresponds to the number of protons in its nucleus, potassium with an atomic number of 19 has 19 protons.
