Name That Group
Metal, Nonmetal, or Metalliod?
100
The number of groups on the periodic table.
What is eighteen?
100
The periods are verticle lines of elements.
What is false? (They are horizontal.)
100
These are horizontal lines of elements on the periodic table.
What are periods?
100
These metals react quickly in air to cover their surfaces with oxides.
What are alkali metals?
100
Iron (Fe) conducts heat and electricity. It is malleable, ductile, and shiny.
What is a metal?
200
This is a group of elements that have similar characteristics.
What is a family?
200
Metals only conduct heat.
What is false? (They conduct both electricity and heat.)
200
The number of periods on the periodic table.
What is seven?
200
These have an oxidization number of 0, preventing them from forming compounds easily.
What are noble gases?
200
Carbon (C) doesn't conduct either heat or electricity, is not malleable or ductile, and isn't shiny.
What is a nonmetal?
300
When mixed, these metals create hydroxides and releases hydrogen.
What are alkali metals?
300
Halogens are extremely active, chemically.
What is true?
300
The number of electrons in an element is equal to...
What is the number of elements in its period?
300
These elements are highly reactive and are not found free in nature.
What are alkaline earth elements?
300
These comprise most of the periodic table.
What is a metal?
400
These lack one electron to complete a shell or subshell, and are extremely active chemically.
What are halogens?
400
As you move to the right across a period, the number of electrons in an element increases.
What is false?
400
This happens to element atoms as they move left to right across a period.
What is decrease in size?
400
These form diatomic molecules when pure.
What are halogens?
400
These do not conduct heat or electricity very well an are usually not malleable or ductile.
What is a nonmetal?
500
The metallic elements found in the second group of the periodic table.
What are alkaline earth elements?
500
Metalliods conduct electricity, but not heat, and are used in technology such as laptops and iPods.
What is true?
500
Within a given period, the chemical activity of metals increase with...
What is the group number?
500
These were considered inert gases until the 1960s because of their low oxidization number.
What are noble gases?
500
Astatine (At) contucts electricity, but not heat. It is shiny, but not malleable or ductile.
