WebThe atomic mass unit (u or amu) is a relative unit based on a carbon-12 atom with six protons and six neutrons, which is assigned an exact value of 12 amu's (u's). This is the … Web2 de sept. de 2024 · 1 H, 2 H, 3 H Answer The element symbol for oxygen is O and its atomic number is 8. The mass numbers for oxygen must be 8 + 8 = 16; 8 + 9 = 17; 8 + 10 = 18. The nuclear symbols are written this way (again, pretend the superscript and subscript are sitting right on top of each other beside the element symbol): 168 O, 178 O, 188 O
How to Determine the ATOMIC NUMBER & MASS NUMBER
Web2 de jun. de 2024 · So, what you need to do is round the atomic weight to the nearest whole number to get a mass number for your calculations. For hydrogen, 1.008 is closer to 1 than 2, so let's call it 1. Number of Neutrons = Mass Number - Number of Protons = 1 - 1 = 0 For zinc, the atomic weight is 65.39, so the mass number is closest to 65. Web26 de nov. de 2024 · The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol. For 12 C, the atomic mass is exactly 12u, since the atomic mass … two meal a day
