Define Chemical bond
Define Ionic bond
The electrostatic force that holds oppositely charged particles together in an atomic compound
Define Metallic bond
The attraction of a metallic cation for delocalized electrons
Define Covalent bond
Define Molecules
Define Formula unit
The simplest ratio of ions represented in an ionic compound
What is a oxidation number
The positive or negative charge of a monatomic ion.
Define polyatomic ion
An ion made up of two or more atoms bonded together that act as a single unit with a net charge.
Define Lewis structure
A model that uses electron-dot structures to show how electrons are arranged in molecules.
Define electrolyte
An ionic compound whose aqueous solution conducts an electrical current..
Define monatomic ion
an iron formed from only one atom.
A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together is called a
What is the difference between polar and nonpolar?
An _____________ forms when neutral atoms gain or lose electrons from their outer valence shell.
As atoms bond with each other, they ________________________ their potential energy, thus creating more-stable arrangements of matter.
decrease
_____________________________ is a measure of the tendency of an atom to attract a bonding pair of electrons.
According to the Octet Rule and Duet rule, atoms are the most stable when they have a full outer shell of electrons.
True
false
______________ form when atoms gain electrons and form a negative charge.
Anions
Other elements, like oxygen, do not have full outer shells and are non-reactive, meaning they will form chemical bonds with other elements.
True
False
The ________________________________ between positively charged nuclei and negatively charged electrons permits two atoms to be held together by chemical bond.
Electrostatic Attraction
Noble gases, like neon, have full outer shells of electrons that are unstable, meaning they do not combine with other elements and do not form chemical bonds.
True
False
____________________________ can have more than one oxidation number.
________________ form when atoms lose electrons and form a positive charge.
Cations
A neutral group of atoms held together by covalent bonds is a ______________
What are the electronegativity differences between Ionic bonds and covalent bonds.
What states that the main group elements tend to form electron configurations that give them eight electrons in their outer valence shell.
The octet and duet rules only apply to main group elements, which include the first two and last six groups in the periodic table.
True
False
Ionic compounds made of only two elements are called __________________ ionic compounds.
