Animals are Our Lives “Clearly‚ animals know more than we think‚ and think a great deal more than we know.” - Irene M. Pepperberg.

For example‚ in the chapter‚ “Dogs Make Us Humans” from the

A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions‚ the London dispersion force and hydrogen bonding
