WebHelium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. WebB) Density rises. C) Temperature rises. D) Pressure rises. E) ALL OF THE ABOVE. A newly formed protostar will radiate primarily at which wavelength? infrared On an H-R diagram, a protostar would be: above and to the right of the main sequence. What is the force that keeps a main sequence star from collapsing on itself? Radiation pressure WebJun 1, 2016 · Let's calculate the atomic radius of polonium, which has molar mass = 209 g/mol, density = 9.32 g/cm3, and exists in a simple cubic unit cell. We see that there is 1 atom per unit cell ( 1 8atom at each corner) and that the edge length of the cell ( a) is … Linear mass density is the amount of mass per unit length.
