When is an atom stable?
Full outer energy level
With 2 or 8 valence electrons
When protons equals electrons
When it has more electrons than protons
Which type of atom will always lose valence electrons to become stable?
Which of the following is not a property of an ionic bond?
Tends to burn
High melting and boiling points
Conducts electricity when dissovled
Covalent Bonds are usually formed by what type of atoms?
Metals and nonmetal
Which type of bond shares electrons equally?
Metals are malleable and ductile because...
The electrons roam free
The electrons are transferred from one atom to another
The electrons are shared between atoms
Which type of bond would have an electronegativity difference 1.8 or larger
Which of the following would not be helpful in identifying the bond type?
The type of elements
The properties of the substance
The difference in atomic mass
Which of the following does not relate to a polyatomic ion?
having an oxidation number
made of nonmetals
forms metallic bonds
What information is gained from the oxidation number?
The number of electrons lost or gained to become stable
The identity of the element
The number of protons and electrons
Which of the following compounds would most likely burn?
Which of the following contains a polyatomic ion?
Which of the following does not apply to an oxidation number of 2-

electrons were gain
electrons were lost
An atom which loses electrons would be called a(n)...
What is unique about Metalloids?
The have properties of both metals and nonmetals
They are the most abundant type of element
They are nonreactive and always stable
