Answer to Question #106599 in General Chemistry for ally

Question

three types of bonds (compounds) Ionic, Covalent and Metallic.

Answer 1

Ionic bonds are bonds that arise due to the formation of ions and are held together due to electrostatic interaction. So, this type of bonds is characteristic of gleam atoms with a high difference of electronegativities (from 1.7 to 2.2, depending on the source of the literature. Reference values ​​differ in different references); most often between metal and non-metal.

Example: KCl, NaNO₃

A covalent bond arises between the atoms of chemical elements with a low difference in electronegativity or its absence. Non-polar (the difference is electronegative from 0 to 0.3-0.5 U depending on the source of the literature) and polar (over 0.3-0.5 to 1.7-2.2., Depending on the source of the literature) are distinguished. It arises due to the formation of generalized electronic and is retained due to the formation of a stable eight-electron structure (similar to an inter-gas).

Example: non-polar H₂, P₄ polar H₂O, NH₃

A metallic bond arises in metals and their alloys due to the formation of a generalized electron field.

Example: Au, Rb, malachite
