The average mass of a single silicon atom in grams is the ratio 28,085/6,022140857.10e23.
Silicon atoms, atomic number 14, have 14 protons in the nucleus. The neutral atom then has 14 electrons. Silicon 28 the most common isotope of silicon has 14 neutrons in the nucleus giving a mass number of 28. The atomic mass of silicon 28 relative to carbon12=12. is 27.9769265325(19)
Silicon is a non metal element. Atomic mass number of it is 28.
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
The mass number is 30.

The mass number is 26. This is the isotope silicon-26 with the atomic number 14.
Mass number is the sum of protons and neutrons in the nucleus of an atom. The atomic number of silicon is 14, so the number of protons in the nucleus of a silicon atom is 14. If the isotope of silicon has 14 neutrons, then the sum of protons and neutrons is 28.

NOT only 15 but 14 is more common (92%)Explanation:Si (atom number 14) has three naturally occurring isotopes with mass numbers:28 (92%), 29 (5%), and 30 (3%).They have respetively 14, 15 and 16 neutrons.(This is because 'mass number' minus 'atom number' equals 'neutron number')
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

14
the mass number is number of protons in an atom, plus the number of neutrons.
