A force of attraction between two atoms which holds the atoms together in a stable configuration.
Chemical bond
A bond in which two electrons are shared between two atoms.
Covalent Bond
A positive to negative attractive force between positive and negative ions that holds an ionic compound together. Electrons are transferred not shared.
Ionic Bond
An electrical force of attraction between oppositely charged ions. It binds the ions together to make a compound. The bond is formed when electrons are transferred from the metal to the nonmetal.
Ionic Bond
A substance composed of oppositely charged ions in a fixed proportion.
Ionic Compound
A substance composed of oppositely charged ions in a fixed proportion.
Ionic Compound
The cation is always ____ and the anion is always _____ in an ionic compound
a metal, a nonmetal
Groups of atoms that stay together and have a positive or negative charge. They are stable as they do not fall apart.
Polyatomic Ions
A group of atoms united by covalent bonds
Molecule
A substance made of molecules
Molecular Substance
Show the kinds and numbers of elements in a compound.
Molecular Formula
A diagram that depicts how the atoms in a molecule are bonded to each other by showing the covalent bonds.
Structural Formula
The ability of an atom in a molecule to attract shared electrons to itself.
Electronegativity
Which element has the highest electronegativity?
Flourine (4.0)
What is the range of the electronegativity scale?
(0.7-4.0)
A bond in which electrons are shared equally between the atoms. The two bonded atoms are identical or have equal electronegativities.
Nonpolar Covalent Bond
A bond between two atoms in which the electrons are not equally shared. One atom has a much higher electronegativity than the other atom. The electronegativity difference must be between 0.5 and including 2.0.
Polar Covalent Bond
Atoms will gain, lose, or share electrons in order to acquire a complete set of 8 valence electrons.
Octet Rule
Tells the kind of atoms and number of atoms (subscript) in a molecule
Chemical formula
