100
The ability of an object to transfer heat or electricity to another object.
What is a conductor?
100
An element's reactivity depends greatly on how many of these are lost, shared, or gained. These also have a negative charge.
What is electron?
100
Helium, neon, argon, and krypton are all part of the last group called this.
What are the noble gases?
100
Is often a gas.
What is a nonmetal?
100
Name the compound N2.
What is nitrogen?
200
Solid nonmetals will often do this when hammered.
What is shatter?
200
This is the most reactive group of metals.
What are the alkali metals?
200
Iron, gold, silver, and zinc are elements of this group.
What are the transition metals?
200
Contains the most elements in the periodic table.
What are metals?
200
The number of hydrogen atoms in the molecule C6H12O6.
What is 12?
300
Most of these are good conductors of electricity, ductile, malleable, solid, and shiny.
What are metals?
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 the 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 is called a __________.
What is a molecule?
400
Most nonmetals are in this state of matter at room temperature.
What is gas?
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 the halogens?
400
These elements tend to give away electrons.
What is a metal?
400
Each element is given a specific _________________ that usually consists of one or two letters.
What is chemical formula?
500
Only one nonmetal and one metal are in this state of matter at room temperature.
What is liquid?
500
This family is a highly reactive group of nonmetals.
What are the halogens?
500
Magnesium and calcium are in the second column and belong to this group.
What are the alkali earth metals?
500
These are found along a zigzag line on the periodic table.
What is a metalloid?
500
A molecule formed from two or more different elements that are chemically combined.
What is a compound?
