Chemical Bonds: Types and Properties Flashcards
¿What is ionic bonding?
A type of chemical bond that forms between atoms with significant differences in electronegativity, where one atom gives up electrons to another.
This type of bond results in the formation of positively and negatively charged ions that attract each other.
¿What characterizes the metallic bond?
In this type of bond, electrons are shared among many atoms in a “cloud” of free electrons.
This gives rise to properties such as electrical conductivity and malleability in metals.
¿What is the relationship between the strength of a bond and its length?
As the bond strength increases, the bond length tends to decrease.
This is because the atoms are more attracted to each other.
¿What characterizes the covalent bond?
It is formed when two atoms share electrons.
This type of bond can be polar or nonpolar, depending on the difference in electronegativity between the atoms.
¿What is the difference between a polar and a non-polar covalent bond?
Polar covalent bonding is formed between atoms with different electronegativities, generating a dipole.
In contrast, non-polar covalent bonding occurs between atoms with similar electronegativities, sharing electrons equally.
