Metal, Nonmetal, or Metalloid?
Molecules
100
The ability of an object to transfer heat or electricity to another object.
What is conductivity?
100
An elements reactivity depends greatly on how many of these are lost, shared, or gained. These also have a negative charge.
What is an electron?
100
Helium, neon, argon, and krypton are all part of the last group called this.
What are noble gases?
100
Is often a gas.
What is a nonmetal?
100
Name the compound N2.
What is nitrogen?
200
The ability of a substance to be pulled out, or drawn, into a long wire.
What is ductility?
200
This is the most reactive group of metals.
What is the Alkali Metals?
200
Iron, gold, silver, and zinc are elements of this group.
What are transition metals?
200
Contains the most elements in the periodic table.
What are metals?
200
The number of hydrogen atoms in C6H12O6.
What is 12?
300
Most of these are good conductors of electricity, ductile, malleable, solid, and shiny.
What is a metal?
300
This family is not very reactive and does not ordinarily form compounds.
What are the Noble gases?
300
The first group of the periodic table contains sodium and potassium. They belong to this group.
What are Alkali Metals?
300
Poor conductors of heat and electricity.
What is a nonmetal?
300
A group of two or more atoms that are held together by chemical bonds.
What is a molecule?
400
At room temperature, more than half of these are gases.
What is nonmetals?
400
The chemical reactivity of metals tends to ________________ from left to right across the periodic table.
What is decrease?
400
Fluorine, chlorine, bromine, and iodine are part of a family called this.
What are Halogens?
400
These elements tend to give away their electrons.
What are metals?
400
Each element is given a specific _________________ that usually consists of one or two letters.
What is a chemical symbol?
500
A substance that will conduct electricity only under certain conditions is called this.
What is a semiconductor?
500
This family is a highly reactive group of nonmetals.
What is the Halogen family?
500
Magnesium and calcium are in the second column and belong to this group.
What are Alkaline Earth Metals?
500
These are unique because many are semiconductors.
What are metalloids?
500
A molecule formed from two or more different elements that are chemically combined.
