How many neutrons does K 42 have?
23
This particular isotope of potassium-42 contains 42 nucleons (i.e., protons and neutrons, combined;) Like other isotopes of potassium 19 out of these nucleons are protons; the rest 42−19=23 are therefore neutrons.
How many protons neutrons and electrons are in a K 42 isotope?
This means that potassium alone contains 19 protons and electrons and 20 neutrons.
How many neutrons does 39K have?
Main Isotopes of Potassium There are 25 known isotopes of potassium, three of which occur naturally: 39K (93.3%), 40K (0.0117%), and 41K (6.7%). Potassium-39 is composed of 19 protons, 20 neutrons, and 19 electrons.
What is the neutron number of carbon?
six neutrons
Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
How many neutrons does potassium have?
20 neutrons
The element of potassium has the symbol K. The nucleus of an atom of potassium contains 19 protons and 20 neutrons.
How is potassium-42 used?
n. An artificially produced beta-emitting isotope of potassium having a half-life of 12.36 hours; it is used as a radioactive tracer in studies of potassium distribution in bodily fluids.

How many neutrons are found in carbon 13?
7 neutrons
Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes.
How do you find neutrons in carbon?
Another common element, carbon, also has several isotopes. The normal carbon atom, atomic number 6, has an atomic mass of 12. Using the formula, atomic mass minus atomic number equals number of neutrons, shows 12-6=6, so the carbon-12 atom has 6 neutrons.
How many neutrons are there in potassium 41?
22
Potassium-41 – It has 19 protons and atomic mass is 41. Hence, number of neutrons is 41 – 19 which is 22.
How many neutrons and electrons are in potassium-40?
Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons. Traces of K-40 are found in all potassium, and it is the most common radioisotope in the human body. K-40 is a radioactive isotope of potassium which has a very long half-life of 1.251×10 9 years and undergoes both types of beta decay.
What are the mass numbers of potassium isotopes?
Mass numbers of typical isotopes of Potassium are 39; 41. There are 25 known isotopes of potassium, three of which occur naturally: 39K (93.3%), 40K (0.0117%), and 41K (6.7%). Potassium-39 is composed of 19 protons, 20 neutrons, and 19 electrons. Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons.
What kind of electron configuration does potassium have?
Electron configuration of Potassium is [Ar] 4s1. Possible oxidation states are +1. Potassium is one of the alkali metals. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a cation, which combines with anions to form salts.
How many electrons are in the valence shell of potassium?
The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Potassium is [Ar] 4s1. Possible oxidation states are +1.
