Compounds & Mixtures - Cornell Notes Flashcards
True or False?
Compounds have similar physical and chemical properties to their individual elements.
False
Electrons ready to bond are called
Valence electrons
Formed when one or more electrons are transferred from one atom to another
Ionic bond
When an element loses an electron, it becomes
Positively charged
When an element gains an electron, it becomes
Negatively charged
The attraction between two oppositely charged ions
Ionic bond
Positively and negatively charged atoms
Ions
Occur when electrons are shared by atoms
Covalent bond
Nonmetal + Nonmetal =
Covalent bond
Metal + Nonmetal =
Ionic bond
In a Louis Dot Diagram, shared electrons are represented by a(n)
Dash
The structure that forms when atoms are joined by covalent bonds
Molecule
Intermolecular forces of attraction that occur between oppositely charged regions of nearby molecules
Van der Waals forces
The universal solvent
Water
Why is water the universal solvent?
Its polarity gives it the ability to dissolve both ionic and other polar molecules (due to like charges)
