What is the relative mass of an electron and a proton? What are the mass and charge of a proton? Where is it located in an atom? Which subatomic particle has a relative mass of 1839 if the mass of an electron is 1? a. proton b. neutron c. electron ...
What is the molecular mass of atomic hydrogen? A hydrogen atom is in the 6 g state. What is the energy of the atom? (a) What is the energy equivalent of the mass of a hydrogen atom ^1H? (b) What is the energy equivalent of the mass of a helium atom ^4He? How many atoms of...
so they are assumed to have a negligible effect. Consequently, the nucleus accounts for almost the entire mass of the atom of any element, which means that a single proton or neutron has an approximate mass of 1 AMU.

The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. Alternatively, the relative atomic mass of an element is given by the mass of one atom of the element1/12 of the mass of one atom of ...

The energy required to separate particles from a molecule or atom or nucleus,equals the mass defect. 为从一个分子或原子或核子中分离颗粒所必须的能量,等同于质量亏损。 权威例句 mass defect mass defect Mass Defect On the Mass Defect of Helium ...
As molar mass and atomic mass are equal for individual atoms, molar mass can be used to measure the particle's identity. For example, the atomic mass of He is 4. Helium is found as monoatomic in nature, meaning that it has only one atom, so its molar mass is also 4....
