The mass number of carbon-12 is 12. This means there are six protons and six neutrons in the nucleus of a carbon-12 atom. Isotopes of an element are...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your...
Isotopes are atoms of the same element that have a different number of neutrons. They can be identified because they will also have a different mass number, or the mass of one atom of the element. Answer and Explanation:1 The mass number for carbon is 12amu. The mass number is the sum...
Atomic number = number of protons # protons = # electrons IN NEUTRAL ATOMS. Today in Physical Science Chemistry: Inside the Atom Chapter 3 Part 2. How Atoms Differ Atoms differ in the number of protons they have. – Oxygen has 8 Protons, Fluorine 9 Protons, First 20 Elements in the...
The first of these lepton numbers is the electron number, defined for any state by Le≡N(e−)−N(e+)+N(νe)−N(ν―e), where N(e−) is the number of electrons present, N(e+) is the number of positrons present and so on. For single-particle states, Le = 1 for e...
To determine how many electrons are present in an atom with an atomic number of 20 and a mass number of 42, we can follow these steps:1. Understand the Atomic Number: The atomic number of an element is defined as the number of
(I) The maximum number of the electrons that can be present in any shell is given by the formula 2n2 where, n is the number of energy level. (II) The maximum number of electrons that can be accommodated in the outermost shell is 8. Electrons are filled in the shells in a stepwis...
Each atom of carbon has 6 protons and electrons. The element naturally exists as a mix of three isotopes. Most of this carbon has 6 neutrons (carbon-12), plus there are small amounts of carbon-13 and carbon-14. Carbon-12 and carbon-13 are stable. Carbon-14 is used forradioisotope dat...
The measured SE energy spectra were fitted by assuming a P贸lya distribution for the simultaneous n -SE emission probabilities. For our previous data with a couple of the carbon foils with different thicknesses, a similar analysis has been carried out. As a result, it was found that the ...
For example, carbon-12 would be written126C in nuclear notation, but the isotope carbon-13 would be written136C. So then how many electrons, protons and neutrons does carbon-13 have? The number of protons and electrons is the subscript (6). ...
How many electrons does carbon-12 have? What is the atomic number for hydrogen? The atomic number of carbon is 6. What is the mass number of a carbon atom with 5 neutrons? Carbon-14 has an atomic number of 6. How many electrons does it have?
