WebJul 17, 2024 · The relative formula mass (aka the formula weight) is the sum of the atomic weights (not average atomic masses) of the atoms in the formula of a compound. It, unlike the formula mass, is a dimensionless quantity. It does not have any unit. Both the quantities have the same numerical value, they only differ in the unit. WebApr 22, 2024 · That is a very old idea to think of the mass “as if it increases” with speed. Which works ok in a limited way, such as getting to E=mc^2. But modern science accepts the idea is incorrect in application and mass should be understood as intrinsic and unchanging with speed. Only momentum “p” or ‘mv’ is factored to increase with speed ...

WebJul 29, 2024 · As you learned, the mass number is the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is an integer that is approximately equal to the numerical value of the atomic mass. Although the mass number is unitless, it is assigned units called atomic mass units (amu). WebScience Chemistry Atomic Structure: 6. In what respect does an atom of magnesium differ from a magnesium ion (Mg2+)? (A)The ion has a more stable electronic arrangement than the atom. (B)The positive charge on the nucleus of the ion is two units greater than the nuclear charge on the atom. (C)The ion has two more protons than the atom.
