Substances that uses ionic bonds are hard, brittle, and has high boiling and melting points.
What are the properties of ionic bonds?
100
Forms when atoms share electrons.
How does covalent bonds form?
100
This bond could bend metal, reshape metal, and conduct electric currents.
What can a metallic bond do?
100
Bonds that form between positively and negatively charged atoms, which they form when atoms are transferred from one atom to another.
What is an Ionic Bond?
100
There are eight electrons on the ______ and _______ clouds.
Second and Third
200
Negative Ions
When atoms gain electrons it is called?
200
It is usually made up of two or more joined atoms.
What is molecule?
200
Positive ions are in fixed positions while negative ions are free to move around.
What is the movement of electrons through metal.
200
An attraction between positively charged metal ions which a sea of electrons are shared.
What is a metallic bond?
200
It depends on the amount of _______ _______ for bonding to occur.
Valence Electrons
300
Positive Ions
When a atom loses a electrons what is it called?
300
A large amount of energy is needed to lose an electron.
How much energy is needed for a atom to lose a electron?
300
Electrical conductivity, malleability and ductility.
What are basic properties of metals.
300
When atoms share one or more pairs of electrons.
What is a Covalent Bond?
300
The group determines.
What determines the amount of valence electrons?
400
Once ionic bonds bond it forms a crystal lattice. (a regular pattern which a pattern is arranged.
After an ionic bond forms what is it called?
400
Substances that uses covalent bonds has low melting points and boiling points, and they are brittle when they are solid.
What are properties of covalent bonds?
400
Electrons move in all direction since they are overlapping.
How does the electrons move in metal atoms?
400
The number of electrons in the outer shell of the atom.
What is a valence electron.
400
Wants a full cloud of electrons.
What is a valence electron?
500
When atoms gain electrons their amount of energy used is determined by the amount of valence electrons. When atoms lose electrons the energy needed is based on the group the atom is in.
How much energy is it required for gaining or losing electrons?
500
A diagram that predicts how covalent bonds might form and how they will bond. (contains a symbol and dots around the symbol to symbolize the number of valence electrons).
What is an electron-dot diagram?
500
Forms when metal atoms lose electrons.
How does a positively charged metal form ions?
500
Joining of atoms to form a new substance.
What is Chemical Bonding?
500
Valence electrons gains, loses, or shares electrons through ionic, covalent and metallic bonds.
What are the types of chemical bonds that valence electrons uses to gain, lose or share electrons.
