When another element is added to another such as: silicon and silicon oxide; why does the structure of particles/atoms change?

Hi! When chemical reactions take place, elements bind to each other to form entirely different compounds. There are a number of different types of covalent bonding, such as ionic, metallic and compound bonding, all of which usually involve the transfer of electrons. A summary of each is: 1. Ionic bonding - the exchange of electrons between a metal and a nonmetal 2. Metallic bonding - bonding between two or more metal ions 3. Covalent bonding - bonding between two non metals hope that helps!

CHEMISTRY ⚛️How does an atom of lithium form an ionic bond with an atom of chlorine?
Lithium ‘loses’ its valence electron and forms a positive lithium cation. Chlorine ‘gains’ that electron and forms a negative chloride anion. The op...

If you know that I is CO2, then you can probably already guess which anion it must have come from it in the reaction with the nitric acid.... All yo...

Hi Addie. I hope you are well. Since the 'gas I' can turn the limewater milky, it must be carbon dioxide gas, meaning the crystalline solid is a car...
