Atoms have a central nucleus with positively charged protons and neutral neutrons; negatively charged electrons circle the nucleus. The electrons that are involved in chemical bonding are those electrons in the outermost orbit, referred to as valence electrons
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion
An atom is considered to be stable of it has 8 valence electrons. The octet rule refers to the the fulfilling of an atoms to have an 8 valence electrons on its valence shell.
Alkanes. Alkanes, hydrocarbons in which all the bonds are single, have molecular formulas that satisfy the general expression CnH2n + 2 (where n is an integer).
The IUPAC name of the simplest alkyne, HC? CH, is thus ethyne, which is derived from ethane. Ethyne is more commonly known as acetylene; it is an extremely important starting material in commercial chemical synthesis.
Ethanol (or ethyl alcohol) is the type of alcohol that over two billion people drink every day. This type of alcohol is produced by the fermentation of yeast, sugars, and starches. For centuries, people have consumed ethanol-based drinks, such as beer and wine, to change the way that they feel.
