Chemical Bonding Flashcard

Front

Chemical bond

Back

A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together.

Front

Which type of chemical bonding results from the electrical attraction between cations and anions?

Back

Ionic Bonding

Front

What characterizes a nonpolar-covalent bond?

Back

A covalent bond in which the bonding electrons are shared equally by the bonded atoms.

Front

What is a molecule?

Back

A neutral group of atoms that are held together by covalent bonds.

Front

What is the difference between a chemical formula and a molecular formula?

Back

A chemical formula indicates the relative numbers of atoms of each kind in a compound, while a molecular formula shows the types and numbers of atoms combined in a single molecule.

Front

Bond energy

Back

The energy required to break a chemical bond and form neutral isolated atoms.

Front

What does the electron-dot notation represent?

Back

The valence electrons of an atom of a particular element.

Front

What are Lewis structures used to represent?

Back

The outermost electron shell in a chemical species like an atom, ion, or molecule.

Front

Single bond

Back

A bond where one pair of electrons is shared between two atoms.

Front

What is resonance in the context of chemical bonding?

Back

The bonding in molecules or ions that cannot be correctly represented by a single Lewis structure.
