Ionic, Metallic, and Covalent Bonds
What is a chemical bond?
A chemical bond is a mutual electrical attraction between the nuclei and valence electrons Of different atoms that bind atoms together
Chemical bonds are important because they make almost everything there is to be such as water (H2O), glucose (C6H12O6), and etc.
Ionic bonds are bonds between metals and nonmetals.
Characteristics: soluble,high melting point, no conductivity as solid but conducts as liquid and when dissolved in water
Ex. NaCl salt
Covalent bonds are bonds between nonmetals and nonmetals.
Characteristics: soluble sometimes, low melting point, does not conduct at all.
Ex. CO2 carbon dioxide
Metallic bonds are bonds between metals and metals
Characteristics: shiny, does not dissolve, high melting point, conducts all the time
Ex. Fe Iron
