What is the periodic table?
100
The positively charged particle in an atom.
What is a proton?
100
This substance's atoms bond together to create something new.
What is a compound?
100
He discovered the atom.
Who is Democrtitus ?
100
This metal has the atomic number of 26 and the abbreviation of "FE"
What is Iron?
200
This section of elements are good conductors of heat and electricity and are ductile
What are metals ?
200
This is the negatively charged particle in an atom.
What is an electron?
200
This can be separated and is made of two or more substances but their atoms do NOT bond together.
What is a mixture?
200
This man came up with the "Law of Conservation of Matter."
Who is Lavoisier.
200
This element's atomic number is 1 and it's abbreviation is "H"
What is Hydrogen?
300
This group of elements have some of the same properties as metals, but also has some properties of non-metals.
What are metalloids ?
300
The neutral particle of an atom.
What is a neutron?
300
This type of mixture means the same through and through and you cannot see the different substances.
What is a Homogeneous Mixture?
300
This man discovered the neucleus of an atom.
Who is Rutherford?
300
This is the only liquid metal and it's Atomic number is "80"
What is Mercury?
400
This group of the periodic table have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solids of these are generally brittle, with little or no metallic luster. Most of these have the ability to gain electrons easily. This group displays a wide range of chemical properties and reactivities.
What are non-metals?
400
Two of the same atoms with a different number of neutrons.
What is an isotope?
400
This type of mixture has larger parts and and the substances are different from each other.
What is a Heterogeneous Mixtures?
400
This man discovered that electrons arrange themselves in an atom based on their energy levels.
Who is Niels Bohr?
400
This metal's atomic number is 79 and it's abbreviation is "AU"
What is Gold?
500
The periodic table has this many elements.
What is 114 elements?
500
This is the center part of the atom that include protons and neutrons.
What is a neucleus ?
500
This process is used to purify liquids.
What is Distillation?
500
This mans theory states all matter is made of atoms and that Atoms are indivisible and indestructible.
Who is John Dalton?
500
This element's atomic number is "22" and it's abbreviation is "TI"
