Ionic Bonds Flashcards
Define an Ion
An atom with a charge (uneven of protons and electrons)
Define octet rule
Atoms form ions/bonds to achieve a full valence shell(8 electrons)
Define Anion
Negative ion(accepts electrons)
Define cation
Positive ion (gives away electrons)
Define polyatomic ion
Molecular ions composed of 2 or more atoms covalently bonded to each other. As a group they have a charge
Define ionic bond
Transfer of electrons creating a cation(+) and a anion(-) opposite charges attract (electrostatic force) holding atoms together
Define lattice structure
Alternating array of oppositely charged ions
True or false: when aluminum forms an ion, it gains three electrons to form a cation
False: it looses three electrons to
True or false: when chlorine forms an ion, it gains one electrons to form to form an anion
True
True or false: when magnesium and oxygen bond, oxygen transfers two valence electrons to magnesium
False: oxygen receives two electrons from magnesium
True or false: ionic compounds are electrically neutral, for every positive charge there is a negative charge
True
True or false: many transition metals form more than one stable cation
True
True or false: in the lattice structure of an ionic compounds each ion is surrounded by ions of like charge
False: each ion is surrounded by ions of opposite charges attract
