For SiS₂, silicon disulfide, the electron dot formula could be seen in the attached picture. The total nonbonding electron pairs in a SiS₂ molecule is: 4 pairs.
<h3>What are the Lewis structure and nonbonding electron?</h3>
The electron dot formula, also known as the Lewis structure, is a representation of the total valence electrons of atoms within a molecule. By writing an electron dot formula, we can visualize the existence of valence electrons and whether they are within bonds or just stand as lone pairs.
The nonbonding electron or the lone pairs are electrons within an atom that are not forming a bond with the other atoms in a molecule. In the SiS₂ molecules, the 4 nonbonding pairs exist both in S atoms.

Explanation:
1. subatomic particles.
2.proton, electron and neutron
3.The atomic mass of an element is actually the sum of the MASSES of protons and neutrons in AN atom of that element
4.An element's atomic number is equal to the number of protons in the nuclei of any of its atoms
5. Number of Protons = Atomic Number
Number of Electrons = Number of Protons = Atomic Number
Number of Neutrons = Mass Number - Atomic Number
For krypton:
Number of Protons = Atomic Number = 36
Number of Electrons = Number of Protons = Atomic Number = 36
Number of Neutrons = Mass Number - Atomic Number = 84 - 36 = 48
6. electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg
7.The center of the atom is called a nucleus
8. Negatively charged particles are found in multiple layers outside the nucleus of the atom. These particles are called electrons, and they orbit in various energy levels around the atom's nucleus.
9. A charged particle is also called an ion
