- Edexcel Structure of the atom
What we need to do to solve this problem is determine how the mass of an electron compares to the mass of a proton or neutron. When the mass of a particle, such as an electron or an atom, is compared to the mass of another particle, it’s called the relative mass.
29 Ιουλ 2022 · Describe the locations, charges, and masses of the three main subatomic particles. Determine the number of protons and electrons in an atom. Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion. Define the atomic mass unit and average atomic mass.
3 Μαΐ 2023 · Protons and neutrons have a very similar mass, so each is assigned a relative mass of 1. Electrons are 1840 times smaller than a proton and neutron, and so their mass is often described as being negligible. The relative mass and charge of the subatomic particles are: The Mass & Charge of Subatomic Particles Table.
The relative masses of atoms are reported using the atomic mass unit (amu), which is defined as one-twelfth of the mass of one atom of carbon-12, with 6 protons, 6 neutrons, and 6 electrons. The atomic mass of an element is the weighted average of the masses of the naturally occurring isotopes.
The relative mass of a proton is 1, and a particle with a relative mass smaller than 1 has less mass. The mass of electrons is very small compared to protons and neutrons.
relative masses. The relative mass of a proton is 1, and a particle with a relative mass smaller than 1 has less mass.
