WebThe mass of a silicon atom in kg is therefore: The volume occupied by a silicon atom: 1. Assuming a transistor is a square sheet made of 10x10 atoms of silicon (radius of silicon atom is 110 pm), the surface area of this sheet is: 1. Au: 1. Cu: 1. Na: 1. C: 4. 1. The energy of the particle in the box can be calculated using the following equation WebAtomic mass of Silicon is 28.0855 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied …

WebThe mass of one atom is usually expressed in atomic mass units (amu), which is referred to as the atomic mass. An amu is defined as exactly 1/12 of the mass of a carbon-12 atom and is equal to 1.6605 \times 10 −24 g. Protons are relatively heavy particles with a charge of 1+ and a mass of 1.0073 amu.
