Potassium has nineteen protons.
Pottasium is a meta element. Atomic number of it is 19.
If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
the reactivity of depends on the number of its outer shell electrons. one all outer shell electrons are there then there is little reactivity. If the atomic number is 19 then the element will 19 protons and 19 electrons. this means it has 2 electrons in the 1st shell 8 in the second 8 in the 3rd and 1 in the last. as it only has one it will be very reactive =)
Fluorine. Number in periodic system = Number of protons
Potassium has nineteen protons.
The element with 19 protons is potassium, which is represented by the symbol K on the periodic table.
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.
19
In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).
Pottasium is a meta element. Atomic number of it is 19.
The element is Neon and the isotope is 10Ne19
If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
Fluorine is a non metal element. Mass number of it is 19.
