Module 4: Chemical Bonds Flashcards
Reactants
Substances that undergo a chemical change.
Products
New substances formed as a result of a chemical change.
Coefficients
Numbers that appear before a formula in a chemical equation to show how many atoms or molecules of each reactant or product are involved in the reaction.
Chemical Bond
A force of attraction between atoms or a group of atoms.
Ion
An atom or a group of atoms that has a positive or negative charge.
Ionic Bonding
A chemical bond formed between oppositely charged ions.
Covalent Bonds
A chemical bond in which 2 atoms share 1 or more pairs of valence electrons.
Covalent Bonds
A chemical bond in which 2 atoms share 1 or more pairs of valence electrons.
Polar Molecules
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
Hydrogen Bond
The positively charged hydrogen side of one water molecule is attracted to the negatively charged oxygen side of another water molecule.
Cohesion
The force of attraction between molecules of different substances so that they tend to stick.
Adhesion
The force of attraction between molecules of different substances so that they tend to stick together.
