Chemistry: Covalent Bonds and Polarity

A series of flashcards summarizing key concepts related to covalent bonds, polarity, and molecular structures in chemistry.

Condensed formula

A simplified representation of a chemical compound showing the arrangement of atoms.

Covalent bond

A bond formed when two atoms share a pair of valence electrons.

Electronegativity

The ability of an atom to attract bonding electrons.

Polar covalent bond

A covalent bond where electrons are not shared equally, resulting in a partial positive and partial negative end.

Nonpolar covalent bond

A type of covalent bond where electrons are shared equally.

Skeletal structure

A simplified representation of a chemical structure that omits hydrogen atoms and indicates bond arrangements.

Electron dot structure

A representation of a molecule that shows the arrangement of electrons around atoms.

3D shape of a molecule

The spatial arrangement of atoms in a molecule, which can be predicted based on the number of bonds and lone pairs.

Polar molecule

A molecule that has a net dipole moment due to the presence of polar bonds.

Partial positive end

The end of a polar covalent bond that has a slight positive charge due to unequal sharing of electrons.

Partial negative end

The end of a polar covalent bond that has a slight negative charge due to unequal sharing of electrons.
