The atomic number of silicon is 14, so the number of protons in the nucleus of a silicon atom is 14. SI Si ›› Calculate the molecular weight of a chemical compound. Silicon crystals for electronics must have a purity of one billion atoms for every non-silicon atom (99.9999999% pure). Because protons and neutrons both are baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. It is found in meteorites known as aerolites.\ It is not found free in nature. Did you mean to find the molecular weight of one of these similar formulas? Question: The weighted average atomic mass of silicon on the periodic table is 28.0855 amu. Mass Percent: Silicon: Si: 28.0855: 1: 46.743%: Oxygen : O: 15.9994: 2: 53.257% ›› Similar chemical formulas. Mass numbers of typical isotopes of Silicon are 28; 29; 30. Enter a chemical formula: Browse the list of common chemical compounds. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.

Mass numbers of typical isotopes of Silicon are 28; 29; 30. SIO2 SiO2 ›› Calculate the molecular weight of a chemical compound.

Note that all formulas are case-sensitive. It's atomic mass is 28.09, meaning that it has 14 protons, 14 electrons, and 14 neutrons. [5] [6] In many parts of the world, silica is the major constituent of sand .

Mass number is the sum of protons and neutrons in the nucleus of an atom. Silicon is a chemical element with atomic number 14 which means there are 14 protons and 14 electrons in the atomic structure.
