These gases are royality as they almost never react with anything and don't associate with "common" elements.
What are the Noble Gases.
200
I contain 6 valence electrons and am yellow in color with a very strong smell. I am often added to natural gas and am often produces when garlic breaks down in the stomach, and you smell me..well you know, when you pass gas..
What is sulfur.

This scientist tested the Thomson model and discovered a small positive particle.
Who is Ernest Rutherford.
200
The periodic law states that the properties of elements are periodic functions of this.
What is the atomic number.
300
This element is a Noble Gas that can be found in some basements. It is radioactive, colorless, odorless, tasteless, but can be a health concern due to its radioactivity.
What is Radon.
300
This family contains metals that are soft enough to cut with a knife and are NEVER found uncombined in nature.
What are the Alkali Metals.
300
This element has 6 energy levels that is a soft, malleable metal. If ingested it is poisonous to humans and animals and can cause brain and nervous systems disorders, even though it was often used in paint and in building materials.
What is lead.

500
I am a gas with 7 valence electrons. I was used in WWI as the first chemical warfare and was known as mustard gas. Today I am used often in pools to kill bacteria.
What is chlorine.
500
This scientist discovered that electrons orbit around the nucleus in fixed orbits and that there are the same number of protons as electrons for an overall electrically neutral atom.
