When an element loses an electron what charge will it have?
positive
Li+NO3
LiNO3
Dot structure for Na+Cl
NaCl
What does malleable mean?
They will bend in different shapes without breaking.
What is an alloy?
Mixture of 2 or more elements (at least 1 is metal)
What types of elements form negative ions?
Nonmetals
Calcium Hypochlorite
Ca(ClO)2
Ba+N
Ba3N2
What do the outer shell electrons become? (Think of how they move)
Delocalized
Why do noble gases not participate in ionic bonding?
They already have a full shell of valence electrons
In an ionic bond how are electrons distributed?
Donated
Aluminum Cyanide
Al(CN)3
Li+Al
No
Why dont metal ions repel each other in metallic bonding?
They are attracted to the negative sea of electrons
What is the electrostatic forces of attraction between the negative sea of delocalized electrons and the positive metal ions?
Metallic bonding
Which element is capable of forming multiple ions with different charges?
any transition metal
Na+CrO4
Na2CrO4
Potassium Oxide
K2O
Why do metals have high melting/boiling points?
The forces of attraction between the metals and electrons are so strong it takes a lot of energy to break them apart.
Cobalt (V): What does the V mean?
The charge of Cobalt
When an element gains or loses and electron it is called:
Ion
Iron (III) Carbonate
Fe2(CO3)3
Iron (II) Phosphide
Fe2P3
Why are metals malleable and ductile?
The layers of metal ions can slide over each other when a force acts on it.
2 types of alloys
Substitutional, interstital
