How many neutrons does silicon have?
The atomic number is equal to the number of protons in the atom, therefore silicon has 14 protons. In a neutral species, the number of protons equals the number of electrons so silicon also has 14 electrons. The mass number is the number of protons plus neutrons, therefore 28 – 14 protons equal 14 neutrons.

What are the first 20 elements of the periodic table?
The first 20 Elements of the Periodic Table: Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminium, Silicon, Phosphorus, Sulphur, Chlorine, Argon, Potassium, Calcium. The symbol for sodium is "Na".
How do you find the atomic number?
The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.
What is the use of silicon-29?
Silicon-29 isotope is used for studies of impurities and intrinsic defects in semiconductors; Silicon-29 isotope is used for studies of irregularities in materials such as glass, crystals and ceramics via methods of electron paramagnetic resonance (EPR);
Who discovered Silicon 28?

Does a silicon atom have 14 electrons?
In order to write the Silicon electron configuration we first need to know the number of electrons for the Si atom (there are 14 electrons).
How do you find number of neutrons?
You can simply subtract the atomic number from the mass number in order to find the number of neutrons.
