|
|
||||
|---|---|---|---|---|---|
| a mutual electrical attraction between the nuclei and valence electrons of different atoms that bind the atoms together | chemical bond
🗑
|
||||
| why do atoms bond? | they are trying to reduce their potential energy. they want to be in a more stable state.
🗑
|
||||
| what determines the type of bond formed? | the way in which the electrons are redistributed
🗑
|
||||
| chemical bonding that results from the electrical attraction between large number of anions and cations | ionic bonding
🗑
|
||||
| results from the sharing of electron pairs between 2 atoms | covalent bonding
🗑
|
||||
| electron configuration in which only the valence electronsare shown as dots around the element's symbol | electron dot notation
🗑
|
||||
| state the octet rule | chemical compounds tend to form so that each atom, by gaining, losing, or sharing electrons, has 8 electrons in its highest energy level
🗑
|
||||
| covalent bonds where the electrons are shared equally by the bonded atoms resulting in a balanced distribution of electrical charge | nonpolar
🗑
|
||||
| covalent bonds with an uneven distribution of electrical charges bc the bonded atoms have an unequal attraction for the shared electrons | polar
🗑
|
||||
| a neutral group of atoms held together by covalent bonds | molecule
🗑
|
||||
| list the 7 diatomic molecules | H2, N2, O2, F2, Cl2,Br2, I2
🗑
|
||||
| indicates the relative numbers of atoms of each kind of element in a chemical compound by using atomic symbols and subscripts | chemical formula
🗑
|
||||
| formulas in which atomic symbols represent the nuclei and inner shell electrons | lewis structure
🗑
|
||||
| show the types and numbers of atoms combined in a single molecule of a molecular compound | molecular formula
🗑
|
||||
| formula indicates the kind, number, arrangement, and bonds but not the unshared pairs of electrons of the atoms in a molecule | structrual formula
🗑
|
||||
| the simplest collection of atoms from which an ionic compound's formula can be established | formula units
🗑
|
||||
| ionic compounds usually exist as___ | crystalline solids
🗑
|
||||
| the orderly arrangement of ions in an ionic compound | crystal lattice
🗑
|
||||
| creates the ability for metals to be good conductors of electricity in the solid state | metallic bonding
🗑
|
||||
| the attraction between the metal's atoms anad the surrounding sea of electrons | metallic bonding
🗑
|
||||
| the measure of the ability of an atom in a chemical compound to attract electrons | electronegativity
🗑
