Periodic Table
The seven horizontal rows of the Periodic Table.
What is a period?
The process of conducting an electrical current.
What is electric conductivity?
Neutral/No charge
Neutrons
The number of protons in an atom.
What is the atomic number?
A process when atoms are broken and new bonds are formed
What is a chemical reaction
The creator of the Periodic Table.
Who is Dmitri Mendeleev?
These are types of elements that can conduct electricity while these elements can't conduct electricity as easily.
What are metals/nonmetals?
Atomic Mass
Protons plus neutrons
Chemical compound used in a reaction.
What is a reactant?
A substance that contains two or more kinds of elements
What is a compound?
Metalloids have the properties of both metals and nonmetals.
What are the properties of metalloids?
Electrons flow smoothly because these charges are attracted to these charges.
What are negative/positive charges?
Atomic mass subtracted by the atomic number equals...
The amount of neutrons
A subatomic particle that has no charge.
What is a neutron?
A substance that speeds up a reaction
What is a catalyst?
Si is the symbol.
What is the symbol of silicon?
Known as conductors, these can be bumped from 1 atom to the next.
What are electrons?
Rounding off the atomic mas...
...to the nearest whole number to find the atomic mass
Particles found within an atom?
What are subatomic particles?
A substance that takes part in and undergoes change during a reaction
What is a reactant?
Metals and nonmetals differ because they have different physical and chemical properties.
How do elements from the metal and nonmetal groups differ?
These things keep the electrical current going through a copper wire.
What are conductors?
M-n
N=M-n
An atom whose number of electrons does not equal the number of protons
What is an Ion
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons
What is an ion?
