metals
Where can you find the metals on the periodic table?
You can find metals on the left side of the periodic table, or on the left side of the ¨staircase¨.
Which non-metal is separted from the rest of the non-metals?
Hydrogen
Are metalloids characteristics the exact same as metals?
No, they share properties with both metals and metalloids.
What group is hydrogen in, what atomic number is it, and is it a non-metal, metal, or metalloid.
Hydrogen is in group 1a, it´s atomic number is 1, and it is a non-metal.
Define dull.
Not lustrous, doesnt have a shine.
What state of matter do metals tend to be?
Metals tend to be mostly solid.
Where can you find non-metals on the periodic table?
Non-Metals are on the right side of the periodic table, or the right side of the staircase, except for one element.
Where are metalloids on the periodic table?
Metalloids are the middle right and are the staircase.
What group is helium in, what is its atomic number, and is it a non-metal, metal, or metalloid.
Helium is in group 7a, it´s atomic number is 2, and it is a non-metal.
Define Luster.
Shiny;refers to the way a metal´s surface reflects light.
List five characteristics of metals.
luster, good conductors of heat and electricity, hight melting point, ductile, and malleable.
List five properties of non-metals.
Non-Metals are dull, poor conductors of heat and electricity, low melting point, brittle, and not malleable or ductile.
Are metalloids typically good conductors of heat and electricity?
Yes, metalloids are typically good conductors, although they are not as good as metals but not as bad as non-metals.
What is Neon´s group number, atomic number, and is it a metal, non-metal, or metalloid.
Neon´s group number is 7a, it´s atomic number is 10, and it is a non-metal.
Define brittle
Name two metals that are most commonly used for conducting heat and electricity.
Gold, copper silver, steel, brass, and alluminum.
What makes non-metals good insulators?
They cannot conduct electricity and heat, and they have extremley high resistance to the flow charge round them.
Name three metalloids on the periodic table. (Bonus 100 of you can tell me what Boron, Silicon, arseic are used for.)
Boron, Silicon, Germanium, Aresnic, Antimony,Tellurium, and Polonium.
Boron- Heat resistant alloys, green color in fireworks.
Silicon- can be used in glass and semi-conductors.
Arsenic- Poison (mostly rat poison) and coloring in fireworks.
What group number is Boron, what is it´s atomic number, and is it a metal, metalloid, or non-metal.
Borons group number is 3a, its atomic number is 5, and it is a non-metal.
Define malleable and ductile.
Malleable- A metal that can be hammered down or rolled into thin sheets.
Ductile- A metal that can be stretched or pulled into thin wires.

How many non-metals are on the periodic table?
There are 17 non metals on the periodic table.
How many metalloids are on the periodic table?
There are 7 metalloids on the periodic table.
What group is scandium in, what is it´s atomic number, and is it a metal, non-metal, or metalloid.
Scandium is in group 1b, its atomic number is 21, and it is a metal.
Define insulator.
A material that keeps enerfy such as heat, electricity, or cold from transfering easily through it.
