|
What are Valence Electrons
|
electrons in outer most energy level
|
|
|
What determines the chemical properties of the element?
|
The number of valence electrons
|
|
|
anions
|
gain electrons to get a - charge.
|
|
|
cations
|
lose electrons to get a + charge
|
|
|
What noble gas configuration does the Chloride Ion attain?
|
ARgon
|
|
|
Ionic compounds have what type of bonds formed when what are lost or gained
|
ionic, electrons
|
|
|
ionic compounds are usually SOLIDS with a HIGH melting point
|
given
|
|
|
ionic compounds are composed of METALand NONMETAL elements from the RIGHT and LEFT sides of the periodic table.
|
given
|
|
|
what are metallic bonds
|
bonds that form between +metallic ions and valence electrons
|
|
|
why do transition metals attain a pseudonobel gas configuration and not a nobel gas configuration as it forms cation?
|
ions with three or greater are uncommon and it would need 7 or 11. they can't lose or gain electrons in the 'd' to have the octet.
|
|
|
what does a chemical formula represent
|
a chem. formula shows the kinds and numbers of atoms in a compound.
|
|
|
a chemical SYMBOL represents one of atoms of that element.
|
given
|
|
|
anions end in IDE ina compound. cations end in the same name as element
|
given.
|
|
|
what are polyatomic ions
|
tightly bounded groups of atoms that behave as a unit and carry a charge. i.e. ClO2-. most end it ite or ate. (cyanide and hydroxide) (ammonium)
|
