[Solved] How many neutrons does 21C have Course Hero

Web10 aug. 2024 · Most carbon atoms also have 6 neutrons, giving them an atomic mass of 12 ( = 6 protons + 6 neutrons). Carbon-14 atoms have two extra neutrons, giving them a total of 8 neutrons. What is the electron of carbon 14? Carbon-14 (or 14C) contains six protons, eight neutrons, and six electrons; its atomic mass is 14 amu (six protons and … WebAnswer: is If by 21 c your mean 21 - carbon atoms then Number of neutrons for one carbon atom is 6. .. Number of neutrons for 21 carbon atoms = 21 x6 . = 126.. 11) If by 2 1 6 you mean isotope ac, then the question is wrong as 21c does not exists. But, in a hypothetical situation, if a c exists, it implies the mass number ; A = 21. mitigator sting and bite

4.8: Isotopes - When the Number of Neutrons Varies

Web7 dec. 2015 · 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. WebA neutron is one of the subatomic particles that make up matter. In the universe, neutrons are abundant, making up more than half of all visible matter.It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1839 times greater than that of the electron.The neutron has a mean square … Web19 jan. 2008 · Carbon-13 has 6 protons, 6 electrons and 7 neutrons.
