Silicon is an element that has an atomic number of 14 and has a brittle structure like a diamond. Its diamond cubic-like crystal structure makes it special among the other elements. In this article, we will discuss what is silicon made of, whether is silicone an element or not and how many protons electrons and neutrons does silicon have. If you are a school student then this article is especially for you. Read on to know everything about what is silicon made of and its properties.

1. What are Protons Electrons and Neutrons?

  • A proton is one of the three primary particles that comprise an atom. The nucleus of the atom contains protons. The core of the atom has a small, dense area in it.
  • Protons have a mass of 1 atomic mass unit (AMU)and a positive electrical charge of 1 (+1), making them positively charged particles. They almost entirely make up an atom’s mass along with neutrons.


  • One of the three primary categories of particles that make up atoms is the electron. In contrast to protons and neutrons, which are made up of smaller, more basic particles, electrons are fundamental particles.
  • They belong to a class of fundamental particles known as leptons. The electric charge of each lepton is either -1 or 0. Electrons are very tiny particles.
  • And because an electron’s mass is so little compared to that of a proton or neutron (about 1/2000), it cannot add much to the overall mass of an atom.
  • The electric charge of an electron is -1, which is equivalent to but the opposite of the charge of a proton, which is +1. Since there are exactly as many electrons in an atom as there are protons, the positive and negative charges balance out by canceling each other, leaving atoms electrically neutral.
  • Electrons are present outside the atom’s nucleus, in contrast to protons and neutrons, which are contained inside the nucleus at its center.
  • Negative electrons are drawn to the positive nucleus because they attract each other since they have opposing electric charges. Electrons are continually traveling through the otherwise vacant area surrounding the nucleus, thanks to this force of attraction.


  • Neutrons have no charge. It is neither drawn to nor drawn away from other objects since it carries no charge at all.
  • With one exception, every atom contains neutrons, which are fused with protons and other neutrons to form the atomic nucleus.

Silicone is a synthetic compound used as sealants, adhesives, lubricants, medicine, utensils, thermal insulation, electrical insulation, etc. The artificial compound has silicone fluids, reactive silanes, and silicone polymers. However, the polysiloxane is its main component.

On the other hand, chemically, silicon is an element with the symbol Si and the atomic number 14. Silicon is categorized as a metalloid, and at room temperature, it becomes solid. In the next segments, you will see what is the formula of silicon and what is silicon made of. (See What are the Characteristics of an Element?)

3. What is the Mass Number of Si?

The atomic mass or atomic weight (AMU, g/mol) of Si (silicon) is 28.0855. 

4. What is Silicon Made of?

The most prevalent element in the Earth’s crust, second just to oxygen, is silicon. What is silicon made of? It is an element, it has protons, neutrons, and electrons inside its atom. It is mixed with oxygen as silicon dioxide or with oxygen and other elements as silicates and is found in rocks, sand, clays, and soils. The by-products of silicon are present in water, the environment, several plants, and even certain animals.

Additionally, Silica (silicon dioxide, SiO2) and carbon-containing substances like coke, coal, and wood chips react to form silicon metal. Silica is often received in the metallurgical grade gravel form. (See Sodium Facts: What is Sodium Made of?)

5. What is the Formula of Silicon?

Si is the short form of Silicon. Howver the general formula of silicon polymers is (R2SiO)x. Here R refers to any organic groups. Also, check out What is Sand Chemical Name?

6. How many Atoms does Silicon Have?

What is silicon made of? A single crystal of silicon that weighs about 1 kilogram contains 6.02214084(18) × 1023 atoms. This number came out when physicists determined the volume of silicon by counting the atoms inside a unit of volume. (See How many Oxygen Atoms are in SiO2)

7. How many Protons Electrons and Neutrons does Silicon have?

  • The number of protons in an atom is equal to the atomic number, hence silicon has 14 protons.
  • The number of protons in a neutral species is equal to the number of electrons, hence silicon also has 14 electrons.
  • Since the mass number is calculated as the sum of the protons and neutrons, 28 − 14 protons equal 14 neutrons. 

8. Does Silicon have 16 Neutrons?

A silicon atom, on average, contains 14 protons, electrons, and neutrons. 

9. How many Electron Pairs can Silicon share?

Each silicon atom contains four valence electrons that are shared, generating covalent connections with the four Si atoms around it. Must read How many Electrons can a Carbon Atom share?

10. Does Silicon have 3 Shells of Electrons?

Yes, silicon has 14 electrons which are arranged in different shells. The first shell has 2 electrons, the second shell has 8 electrons and the third shell has 4 electrons. And in silicon’s valence shell, there are 4 electrons present. 

11. How many Protons Neutrons and Electrons does Silicon-30 have?

Silicon-30 has 14 protons, 16 neutrons, and 14 electrons in total. (See what type of ions have name ending in -ide?)

12. How many Protons Neutrons and Electrons does Si 28 have?

Si 28 isotope has 14 protons, 14 neutrons, and 14 electrons. 

13. How many Protons Neutrons and Electrons is in Si 29?

Si 29 isotope has 14 protons, 15 neutrons, and 14 electrons in total. (See How many valence electrons does oxygen have?)

14. How many Neutrons does Silicon 28 have?
