Therefore, a potassium atom contains nineteen protons. We must always remember that the atomic number and the number of protons of an element are equal.
Since potassium is the 19th element of the periodic table, the atomic number of potassium is 19. The elements in the periodic table are arranged according to their atomic number. There are 118 elements in the periodic table and the 19th of these elements is potassium. The diameter of a proton particle is about 2.4 × 10 −13cm. Its actual charge is +1.602 × 10 −19coulombs. That is, the mass of a proton is approximately 1837 times greater than the mass of an electron. However, the actual mass of the proton is 1.6726 × 10 −27kg. The relative mass of protons is 1, which is approximately equal to the mass of hydrogen (1.00757 amu). When a hydrogen atomremoves an electron from its orbit, the positively charged particle that remains is called proton.
It resides in the center or nucleus of the atom. Protons are the permanent core particles of an atom. Therefore, the number of negatively charged electrons orbiting in its orbit is equal to the number of positively charged protons in the nucleus.Ītomic number (Z) = Number of charges in the nucleus (p) How many protons does a potassium atom have? That is, the atomic number is the total number of protons.

This number is equal to the serial number of the periodic table. The atomic number of the element is expressed by ‘Z’. Thus, the number of positive charges present in the nucleus of an element is called the atomic number of that element. He called that number the order of the atoms. The results of his experiments show that each element has a unique integer equal to the number of positive charges in the nucleus of that element. Scientist Henry Gwynn Jefferies Mosle examined the X-ray spectrum of various elements in 1913-to 1914.

How to easily find the number of electrons, protons and neutrons in a potassium atom? Electrons revolve around the nucleus in a specific orbit. The only exception is hydrogen, which has only protons in its nucleus but no neutrons. Experiments by various scientists have shown that the nucleus of an atom contains protons and neutrons. One is the nucleus and the other is the orbit. Atoms can usually be divided into two parts.
