2.3 study guide Flashcards
What does ionic bonding happen between?
metal and nonmetal
What happens to electrons in ionic bonding?
electrons are transferred
What does a polar covalent bond happen between?
nonmetals
What does a nonpolar covalent bond happen between?
nonmetals
What happens to the electrons in a polar covalent bond?
They are shared inequally
What happens to the electrons in a nonpolar covalent bond?
They are shared equally.
Given two nonmetal atoms that are the same element, what bond will form and why?
Nonpolar covalent, atoms have exact same charge
Given a metal and a nonmetal atom, what bond will form and why?
Ionic, only forms with metal and nonmetal
How does electronegativity determine what type of bond two atoms will form?
The atom with the higher electronegativity will attract the shared electrons more strongly. The strength of attraction and atom type determines bond.
How do ionic substances dissolve in water?
Ionic bonds are broken apart into separate atoms when exposed to water.
How do covalent substances dissolve in water?
Covalent substances separate the molecules of a substance, but the bonds still stick together.
