The mass number for silicon-29 is 29. This number represents the total number of protons and neutrons in the nucleus of a silicon-29 atom.
The mass number of silicon is 28. It is calculated by adding the number of protons and neutrons in the nucleus of a silicon atom. Silicon has 14 protons and 14 neutrons, giving it a mass number of 28.
Silicon is a non metal element. Atomic mass of it is 28.
Silicon is a non metal element. Atomic mass number of it is 28.
The mass number of an atom is the sum of its protons and neutrons. In this case, if a silicon atom contains 14 protons (since it is a silicon atom) and 16 neutrons, the mass number would be 14 + 16 = 30.

The mass number of an isotope is the sum of its protons and neutrons. Silicon has an atomic number of 14, meaning it has 14 protons. If the isotope has 15 neutrons, the mass number would be 14 protons + 15 neutrons, which equals 29. Therefore, the mass number of the silicon isotope is 29.
To determine the grams of silicon in the sample, you need to know the molar mass of silicon. Since silicon's atomic mass is approximately 28 g/mol, you can calculate the grams of silicon by dividing the number of atoms by Avogadro's number and then multiplying by silicon's molar mass. This calculation would provide you with the amount of silicon in grams in the given sample.
Silicon has 14 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a silicon isotope = Mass number - 14
The mass number of an atom is the sum of its protons and neutrons. Silicon has 14 protons making its atomic number 14. With 14 neutrons added to 14 protons, the mass number of silicon with 14 neutrons would be 28.
To calculate the mass of silicon in the sample, you would first convert the number of atoms to moles using Avogadro's number. Then, you would calculate the mass of silicon in grams using the molar mass of silicon (28.0855 g/mol). The final mass would depend on the number of atoms in the sample.
