chemical bonds Flashcards
what is a chemical bond?
A chemical bond is the chemical process responsible for the attractive interactions between atoms and molecules, and which confers stability to diatomic and polyatomic chemical compounds. The explanation for such attractive forces is a complex area that is described by the laws of quantum chemistry.
ionic bond
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.
covalent bond
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
metallic bond (sea of electrons)
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
ductile
Covalent bonds occur between two non-metals, metallic bonds is between two metals, while ionic is observed between non-metal and metal. … Metallic bonds are malleable and ductile, while covalent bonds and ionic bonds non-malleable and non-ductile. Bond energy is higher in covalent and ionic bonds than the metallic bonds.
what is ductility?
Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire. Examples: Most metals are good examples of ductile materials, including gold, silver, copper, erbium, terbium, and samarium.
intermolecular forces
Intermolecular forces are the forces that attract molecules or particles to like or unlike molecules or particles. Typically, these forces between molecules form much weaker bonds than those bonds that form compounds. … Ion-dipole bonds (ionic species to covalent molecules) are formed between ions and polar molecules.
