From the periodic table, we see that the atomic number (number of protons) for the element carbon is #6#. The name carbon-14 tells us that this isotope's mass number is #14#. The chemical symbol for carbon is #"C"#. Now write the isotopic notation for carbon-14. #""_6^14"C"# We can determine the number of neutrons as #14-6=8# neutrons. Example 2.
What is number of neutrons in sodium? Updated: 5/26/2024. Wiki User. ∙ 11y ago. Study now. See answers (5) Best Answer. Copy. sodium-11 has 5 proton,5 electron and 6 neutron.
Answer: Well, the mass number of an atom is simply the number of massive, nuclear particles, protons, and neutrons.... And so for 1H, the mass number is simply 1; for 2H, the mass number is simply 2; for 3H, the mass number is simply 3. The isotopes contain 0, 1, 2 NEUTRONS respectively. Most of the heavier atoms have a range of isotopes, and ...
Explanation: See this answer for neon gas. For sodium metal, Z = 11; you should easily be able to quote the number of protons, electrons, and neutrons. Answer link. iOS.
The sum of neutrons and protons, the massive nuclear particles, gives the mass number, with which we often label the elemental symbol as a left hand superscript. But the number of #"nucular protons"#, i.e. #Z#, UNEQUIVOCALLY identifies the atom; #Z=11# for sodium, #Z=10# for neon; #Z=12# for magnesium.
A sodium ion has 11 protons and 12 neutrons. Since it is an ion, it has one fewer electron than protons, so it has 10 electrons. the amount of electrons that sodium has is:11. the amount of ...
In this case, you can say that a sodium-20 isotope contains. 20 protons and 20 − 11 = 9 neutrons. inside its nucleus. Answer link. 11 The most important thing to remember here is that all the isotopes of a given element must have the same number of protons. For a given element, the only difference between its isotopes is given by the number ...
Sodium is element nr. 11, which means 11 protons, so 25 - 11 = 14. Note that there is no actual Sodium isotope with mass 25. The atomic number of sodium is 11, so a mass number of 25 means there ...
Best Answer. sodium's atomic number is 11 and since protons and electrons are the same number as the atomic number, there are 11 protons and 11 electrons, to get the neutrons you take the isotope ...
It would have 2 neutrons. This isotope would be extremely unlikely, and if not extremely short-lived. The mass number is the sum of the massive nuclear particles, the protons and the neutrons. This source relates that the lightest sodium isotope is ""^18Na. You might find ""^13Na as an extremely short-lived isotope in a nuclear reactor - it would undoubtedly be screaming hot.
