What is 39 in potassium?
39 is the atomic mass of one atom of potassium. This is essentially the weight of one atom
How many prtons are presnt in an atom potassium -39?
A potassium-39 atom has 19 protons since the atomic number of potassium is 19.
How many protons does patassium have?
A potassium atom has 19 protons.An uncharged atom therefore has 19 electrons, but in solution many potassium atoms exist as ions (K+), with 18 electrons.
Why calcium is placed after potassium?
The periodic table is arranged by atomic number, which is the number of protons in the nucleus of an atom. Potassium has an atomic number of 19, while calcium has an atomic number of 20. This is why calcium is placed after potassium in the periodic table.
What is the atomic number of KCl?
Potassium chloride (KCl) does not have an atomic number since it is a compound made up of two elements: potassium (atomic number 19) and chlorine (atomic number 17). The atomic number is the number of protons in an atom's nucleus, and since compounds are formed by bonding atoms together, they do not have an atomic number.
What is an atom of potassium's atomic number and mass number?
The atomic number of potassium is 19.The atomic weight of potassium is 39,0983(1).The mass number of the isotope potassium-39 is 39.
How many electrons does an atom potassium havew?
Finding the number of electrons in an atom is easy. You just have to know the atomic number of the element. The atomic number for Potassium is 19. That means Potassium has 19 electrons.
What is 39 in potassium?
39 is the atomic mass of one atom of potassium. This is essentially the weight of one atom
How many prtons are presnt in an atom potassium -39?
A potassium-39 atom has 19 protons since the atomic number of potassium is 19.
An atom of Potassium has a mass number of 40 and an atomic number of 19.how many protons does it have?
The atomic number is the number of protons: 19.number of neutrons = mass number - atomic number = 21.The number of electrons is normally the same as the number of protons: 19
How many protons does patassium have?
A potassium atom has 19 protons.An uncharged atom therefore has 19 electrons, but in solution many potassium atoms exist as ions (K+), with 18 electrons.
How many protons are in pottasium?
Pottasium is a meta element. Atomic number of it is 19.
Why calcium is placed after potassium?

What is atomic number for potassium?
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
How many electrons does a stable atom of potassium have?
Potassium's atomic number is 19. Thus, it has 19 positively charged protons. To make it neutral, it must also have 19 negatively charged electrons.
Do all potassium K have the same atomic number?
Yes. The atomic number is the number of protons in an atom. Potassium always has 19 protons, and so its atomic number is 19. As soon as there is a change in the number of protons, then the element is different.
