{11} Bonding Basics Flashcards
Define:
Chemical Bond?
The force that holds atoms together in a compound
Define:
Chemical Formula?
Aymbolic representation of a comound
EX: NaCl
Define:
Lewis Model?
A simple model of chemical bonding
Define:
Lewis symbol?
An atomic symbol that has the atomic symbol in the center with electrons on the outside
Define:
Formula unit?
The smallest electrically neutral collection of ions
Define:
Ionic Bond?
What type of electron transfer?
A chemical bond formed between two oppositely charged ions, or nonmetals and metals
Atom gives or removes electron to other atom
Define:
Empirical Formula?
A chemical formula that shows the simples whole-number ratio of atoms in the compound
EX: H2O
Define:
Molecular Compound?
A compound composed of two or more covalently bonded nonmetals
Define:
Octet?
A Lewis symbol, with eight dots, filled outer electron shell for s and p block elements
Define:
Lattice energy?
The energy associated with the formation of a crystalline lattice of alternating cations and anions from the gaseous ions
Define:
Covalent bond?
A chemical bond in which two atoms share electrons that interact with the nuclei of both atoms, lowering the potential energy of each through electrostatic interactions
Bond that forms between two or more nonmetals
Define:
Molecular Formula?
A checmical formula that shows the actual number of atoms of each element in a compound
EX: H2O
Define:
Ionic Compound?
A compound composed of cations and anions bound together
Define:
Octet rule?
The tendency for most bonded atoms to possess or share eight electrons in their outer shell in order to obtain stable electron configurations
Define:
Structural Formula?
Uses lines to represent covalent bonds and shows how atoms in a molecule are connected or bonded to each other
** For H2O2: EX: H-O-O-H**
