Atomic Structure of Potassium. The nucleus is made up of 19 protons and 21 neutrons. The nucleus is bound by 19 electrons, with a single, highly unstable electron in the outer shell (ring).
How many neutrons are in the nucleus of a potassium atom with a mass number of 39?
20 Potassium-39 – It has 19 protons and atomic mass is 39. Hence, number of neutrons is 39 – 19 which is 20.
How many atoms are in a potassium atom?
There are 6.022 × 1023 atoms of potassium in every mole of potassium. Since one mole of KOH contains one mole of K, the answer is 6.022×1023 atoms of K.

How many electrons are in potassium?
19 electrons In order to write the Potassium electron configuration we first need to know the number of electrons for the K atom (there are 19 electrons). When we write the configuration we'll put all 19 electrons in orbitals around the nucleus of the Potassium atom.
How do u find neutrons?
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
How many neutrons are in the nucleus of a potassium atom with a mass number of 39 round to the nearest whole number no decimals?
Protons (the atomic number) and neutrons both contribute to the atomic mass. If you therefore subtract the number of protons (19) from the atomic mass (39), you are left with the number of neutrons (=20).
How many neutrons are in potassium-40?
