![]() ![]() It has an estimated density of 40.7 x 103 kg/m3. Therefore, a silicon atom has fourteen protons. The atomic number of an element is equal to the number of protons and electrons in that element. Silicon is the 14th element of the periodic table so its atomic number is 14. The most stable known isotope, 269Hs, has a half-life of approximately 9.7 seconds. Protons, Neutrons, Electrons for Silicon (Si, Si4+, Si4-) Silicon is a classified metalloid element and its symbol is Si. To determine the atomic mass of neon, the average of the isotopes need to be extracted: 0.9048 × 19.992 18.09 amu. The atomic mass unit of the gas is 21.991, and the abundance of the gas is 9.25. It is a synthetic element (first synthesised at Hasse in Germany) and radioactive. neon-22: It is made up of ten protons and twelve neutrons. If uranium (mass number 238 and atomic number 92) emits an a-particle, the product has Mass number and Atomic number What is effective atomic number An atom.
