What is the difference between and element and compound?
Element is only one type of atom; compound is 2 or more elements chemically bound and has different properties than the elements that it is made of.

A student performs a chemical reaction by adding 8 grams of A and an unknown amount of B together: A + B --> C The student finds that 12 grams of C is produced. How many grams of B did the student add?
By the law of conservation of mass, the student added 4 grams of B (8+4=12)
500
If i have 1 valence (outer) electrons what group/family do I belong to?
Alkali Metals
500
Where are the least reactive elements located on the periodic table and why are they least reactive?
Noble Gases (Right side); they have a full set of valence electrons (8)

A newly discovered element needs to be placed on the Periodic Table. Explain what information you would need to correctly place the element in the right group.
You would need to know how its physical and chemical properties, and place it with elements that have similar reactive properties because elements in the same group have similar and chemical properties.

What is the difference between the atomic number and the atomic mass?
Atomic # tells you how many protons and electrons are in elements atom. While the atomic mass tell you how many particles are in the nucleus (protons and neutrons).
