You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebCarbon has 6 protons and 6 electrons in its nucleus and outer shells. The number of neutrons in the nucleus of a carbon atom can vary, which results in different isotopes of the element. Carbon-12 has 6 neutrons in its nucleus and it is one of the most common isotopes of carbon. Other carbon isotopes are carbon-13, with 7 neutrons, and carbon ...

WebThe mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, … WebLi Number of protons = 3 Number of neutrons = 7 − 3 = 4 PL Number of electrons = 3 (always the same as the number of protons) 5 Complete these numbers for a boron atom. Boron 7 lithium The mass number tells you how many protons plus neutrons there are. M Atomic number = Mass number = 5 B boron Number of protons = 11 SA Number of … tachimetr olx
How many protons and neutrons are in lithium? – Sage-Answers
WebTogether, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract … Web29 okt. 2024 · Atomic number = proton count = elemental identity. Being lithium, proton count is 3. A homeostatic lithium would have 3 protons, 3 neutrons, 3 electrons. The … Web7 Li: β − t (0.9(1)%) 5 He: 9 ... with more protons than neutrons. (There are many such unstable isotopes, the lightest being 7 Be and 8 B.) There is only a trace amount (0.000 002 (2)) of 3 He on Earth, primarily present since the formation of the Earth, although some falls to Earth trapped in cosmic dust. tachilek to mandalay bus
