This is Group 1 of the Periodic Table. This group is said to have shiny metals that can be easily cut with a knife. These metals are also very reactive.
What are Alkali Metals?
100
This term describes the ability of a metal to reflect light
What is luster?
100
These elements have physical and chemical properties of both metals and nonmetals
What are metalloids?
100
This man is responsible for the creation of the first Periodic Table of Elements
Who is Dimitri Mendeleev?
100
This element has the atomic number 25 and is found in group 7 on the Periodic Table
What is Manganese?
200
These metals occupy groups 3-12 on the Periodic Table. They are fairly unreactive for metals, making them useful for jewelry and construction.
What are Transition Metals?
200
This term is the ability of a substance to be hammered or rolled into sheets
What is Malleability?
200
This element is not considered a metalloid, but has properties of both metals and nonmetals. It is found in group 1 on the Periodic Table. It is also said to be the most common element in the universe.
What is Hydrogen?
200
In the early 1900s this scientist corrected the issues with the original Periodic Table by listing the elements in order of atomic number.
Who is Henry Moseley?
200
This element is the only nonmetal in group 1 of the Periodic Table.
What is Hydrogen?
300
These are the elements in group 18. These elements were not yet discovered when the first periodic table was developed since they only react under special conditions.
What are Noble Gases?
300
This term is the ability to of a metal to be pulled into thin wires
What is ductility?
300
This particular metalloid is a widely used in making semiconductor devices for computers and other electronic products.
What is Silicon?
300
These elements were undiscovered when the first Periodic Table was developed. They are the last group of elements to be added to the periodic table.
What are Noble Gases?
300
This element is the metalloid with the lowest atomic number.
What is Boron?
400
This is group two of the periodic table. These elements react quickly, although not as quickly as the elements in group one.
What are Alkaline Earth Metals?
400
This extensive group of metals includes gold, copper, and silver. They are typically used for jewelry, electrical wires, and many industrial applications.
What are transition elements?
400
At high temperatures, metalloids conduct electricity like metals. But at low temperatures, metalloids will not conduct electricity.
What is a semiconductor?
400
Before the Periodic Table was arranged in order by atomic number it was first arranged in order by this particular property.
What is Atomic Mass?
400
This element is the only nonmetal that is liquid at room temperature. It has an atomic mass of 79.90.
What is Bromine?
500
Elements that can react with a metal and form a salt. These are found in Group 17 on the Periodic Table and include Chlorine, Fluorine, and Iodine.
What are Halogens?
500
This is the only metal that is liquid at room temperature.
What is Mercury?
500
Carbon, Hydrogen, Nitrogen, and this element make up a whopping 96% of the mass of our body.
What is Oxygen?
500
This term means "repeating pattern" and is the namesake of the Periodic Table. Due to patterns observed by Mendeleev, the Periodic table was arranged into these to show the repeating patterns of melting points, metallic properties, and many other chemical trends.
What is periodic?
500
This element has the highest atomic mass of ALL the elements on the periodic table.
