Ionic bonds are formed between metals and nonmetals, while covalent bonds are formed between two nonmetals.
An ionic bond is formed after two or more atoms donate or gain electrons to form an ion. An ionic bond occurs between a metal that donates electrons and a nonmetal that accepts electrons. Ions with opposite charges attract each other and form an ionic bond. The functions of the following bonds in the human body are shown below. Ionic bonding - the generation of electrical signals and their transmission.
Covalent Bond Holds together the building blocks of important molecules such as DNA. Hydrogen Bonds Hold strands of genetic material together. Only pure covalent bonds occur between identical atoms. Electrons are usually shared, but with a polarity, he spends more time on one atom than on another. Ionic bonds are formed between metals and nonmetals.
