Chemical Reactions

Chemical Reactions

Chemical reactions (their properties, types, flow conditions, etc.), are the cornerstones of an interesting science called chemistry. Let’s find out what a chemical reaction is and what happens in a chemical reaction. So, the chemical reaction in chemistry is considered to be the conversion of one or several substances into other substances. At the same time, the nuclei of atoms do not change (unlike nuclear reactions). During chemical reactions there is a redistribution of electrons and nuclei, new chemical elements appear.

Covalent Bond

Covalent Bond

A covalent bond meaning comes from two Latin words: “co” – jointly and “vales” – valid. Since a covalent bond occurs when a pair of electrons belonging for two atoms simultaneously. The formation of a covalent bond occurs only among the atoms of non-metals, and it can appear both in atoms of molecules and in crystals.

Crystal Lattice in Chemistry

Crystal Lattice

All material substances exist in three basic states: liquid, solid, and gaseous. Yet, there is a state of plasma, which scientists consider to be the fourth state of matter, but our article is not about plasma. Do you know what table salt and a beautiful diamond have in common? Based on their structure, they are both solid objects. The solid objects (whether diamond or salt) have a special crystalline structure; they contain tiny interlocking crystals. This crystalline structure has a certain order, creating a crystal lattice. The crystal lattice is the arrangement of atoms in a crystal.
