Flashcards in Unit 3 Key Terms/Concepts Deck (96)
What are the 4 ways to represent electron configuration?
To find the number of valence electrons in an element, you must know the _____, because they are equivalent (except for Helium)
The group number on the periodic table
what is the maximum number of dots per side in a Lewis configuration
atoms tend to gain, lose, or share
electrons in order to obtain an octet in their valence
shells due to the stability of the ns^2p^6 configuration.
(2+6 = 8; octet = set of 8)
elements that follow the duet rule (not the octet rule)
H, He, Li, and Be
Nonmetals tend to ___ an electron to reach an octet
metals ___ their valence electrons to become cations
a pair of electrons shared between two atoms.
binary covalent compounds.
Compounds containing two different nonmetals that
share valence electrons
a compound is ionic if
the first element is a metal or it starts with the polyatomic ion NH4+ (ammonium ion).
a binary compound is covalent if
the first element in the formula or the name is a
a substance that releases H+ ions (or protons or hydronium ions) in water solutions.
Most acid formulas start with
can produce only one H+ (or proton or hydronium ion) in water
Acids that can produce two or more H+’s in water
Binary acids contain
H and one other element (Not Oxygen)
Binary acids are named according to what pattern
hydro + part or all of element name + ic acid
Ex: HCl hydrochloric acid
Oxyacids (oxoacids) contain
The general formula for oxyacids is
General formula = HnXOm (X is the “central
Oxyacids containing -ate ions end with___
Polyatomic names determine the
Oxyacids containing -ite ions end with
drinking alcohol, ethyl alcohol or ethanol
