These are elements that are usually shiny, good conductors of heat and electricity, and solid at room temperature. Located on the left, center of the periodic table; about 2/3 of all the elements are these.
What are Metals.
100
Particles of different substances arrange themselves into different patterns when they solidify into these. It is a regular, repeating arrangement of atoms, ions, or molecules.
What is a Crystal.
100
This is a covalent compound made up of many small, repeating units linked together in a chain. This pattern is found in DNA.
What is a Polymer.
100
When this is hammered into a sheet or pulled into a wire, it does not break because the ions are in layers. The layers can slide past one another without losing their attraction to their pooled electrons.
What is Metal.
100
The ability of a material to be hammered or rolled into sheets.
What is Malleability.
200
This is malleable, the other is ductile and conducts electricity. The last one is strong and mostly iron.
What is #1 Gold, #2 Copper, #3 Steel.
200
This is the smallest repeating pattern that shows how the atoms, ions, or molecules are arranged in a crystal.
What is a Unit Cell.
200
A small molecule that forms a link in a polymer chain. It is a gas at room temperature. It links up by means of covalent bonds to form a solid polymer.
What is a Monomer.
200
Cells must contain three important kinds of natural organic polymers.
What are proteins, carbohydrates, and nucleic acids.
200
The ability of a substance to be pulled into wires.
What is Ductility.
300
This bond is formed when many metal atoms share their pooled electrons. They can bond to atoms of the same element, or they can bond with other metals.
What is a Metallic Bond.
300
These are six-sided, just as a snowflake is. This is because the molecules that make up these and snowflakes arrange themselves into a hexagonal patterns.
What are Quartz Crystals.
300
This kind of chemical holds polymers together.
What are Synthetic Polymers - polyethylene.
300
This term is used to decribe electrons are free to move throughout the solid.
What is "sea of shared electrons".
300
To perform by turns or in succession.
What is alternate.
400
These are the two properties of metal
What is malleability and ductility.
400
Sodium ions alternate with chloride ions in a three-dimensional pattern. These are the scientific elements.
What is NA+ and Cl-.
400
Compounds based on carbon. The materials of life.
What is Organic Compounds.
400
Stringlike molecules made up of repeating units of monomers.
What is Natural and Synthetic Polymers.
400
Latin for ductilis; means "that may be led or drawn."
What is ductile.
500
The atoms in this naturally crystallized metal are arranged in a regular cubic pattern.
What is gold.
500
How the arrangement of these in the cubic unit cell is reflected in the shape of the magnified crystal.
What is Sodium and Chlorine Ions.
500
Amino acid monomers join together to form this.
What is a protein.
500
This holds sodium chloride crystals together.
What is Ionic Bonds.
500
A pure substance that can be identified by the number of protons in the nucleus of its atoms.
