So for your question, the Periodic Table tells us that potassium has an Atomic Number of 19, so there are 19 protons and 19 electrons. The Periodic Table tells us that potassium has an Atomic Mass of ≈39. So there are 39 - 19 = 20 neutrons. Protons and electrons can be combined into neutrons The formation of such nuclear shells at specific magic numbers of protons or neutrons constitutes the backbone of our understanding of the nucleus. However, scientists are still trying to understand the rules behind when a shell is formed or not. An emblematic situation occurs among nuclei with 32 and 34 neutrons

As electrons are way more lighter than compared to an neutron or proton, we assume mass of electron to be zero. Therefore the mass number of an element is the sum of it's number of protons and neutrons. In your case, 19 protons + 20 neutrons = 39, 39 is the mass number of the given element Determining Numbers of Protons, Neutrons, and Electrons from the Isotopic Notation (5 of 8) Consider the following symbol: 33 16 S 2- The 16 is the atomic number which is the number of protons .

How To Calculate The Number of Protons, Neutrons, and

Determine the number of protons, neutrons, and electrons in a specific isotope of an element. Represent a single isotope of an element using the three main elemental symbolisms. The final subatomic particle was not discovered until 1932. In order to account for the neutral charge of an atom as a whole, the number of positively-charged protons. As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged. The −1 charge of one electron balances the +1 charge of one proton. Both protons and neutrons have a mass of 1, while electrons have almost no mass. Table 2.1 Charges and masses of the particles within atoms The electrons have negative charge and very little mass and are found outside the atom's nucleus. The weight of an atom in atomic mass units is approximately the sum of its protons and neutrons, since the electrons don't have much mass. For example, a typical carbon atom has six protons and six neutrons, and it has an atomic weight of 12 amu In 1911, Ernest Rutherford discovered that at the core of every atom is a nucleus. Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than .01% of the volume of the atom, but typically. neutrons, and electrons in the atom. B is incorrect because a nucleus can contain multiple protons as well as neutrons. C is correct because a neutron has a mass similar to the mass of a proton

Isotopes are different forms of an element that have the same number of protons but a different number of neutrons. Some elements—such as carbon, potassium, and uranium—have naturally occurring isotopes.
