Chemical bonds Flashcards
1
Q
Polar covalent bonds
A
electrons are not shared equally between the 2 atoms because of the difference in electronegativity
2
Q
Ionic bonds
A
in a crystal lattice structure, held together by electrostatic forces between anions and cations. Have a macroscopic structure. The class depends on size and charge of ions
3
Q
What is a polyatomic ion
A
ion composed of 2 or more atoms that are covalently bonded e.g., ClO-, ClO4-
