True or false? Atomic mass is not found on the squares of elements in the periodic table
What is false?
True or false? Atomic theory grew as a series of models that developed from experimental evidence.
What is true?
If an atom has 4 electrons- this means the electrons carry a positive 4 charge?
True or false?
What is false: electrons are negatively charged
Each square in the periodic table shows all of the following except:
the atomic number, chemical symbol, who invented it and atomic mass
what is who invented it?

d. atom
What is d) the atom?
True/false:
Atomic mass of an isotope is always exactly the same:
False: the atomic mass is an average of the isotope
True or false? Atomic theory grew as a series of models that developed from experimental evidence?
What is true?
True or false:
Elements can be expected to react differently to the same thing each time it is tested?
What is false- elements are shown to repeatedly react the same time and time again

Fun Question:
What would your mass be on the moon?
Answer: What is the exact same as it is on Earth? Mass does not change. Weight does!

What is b) plasma
True or false: Neutrons change the mass of an element
What is false- neutrons do not have a charge
