500
The central part of an atom, AND which two particles make it up
What is the Nucleus: Protons and Neutrons
500
What does the Atomic number of an element tell us AND what does the Atomic mass tell us
Atomic Number: Number of Protons (same as electrons) Atomic Mass: Number of Protons PLUS Neutrons
500
Sublime
When a solid turns to a gas WITHOUT turning into a liquid first
500
Can a mixture always be a solution and can a solution always be a mixture? Why?
A solution is always a mixture, but a mixture is not always a solution. A solution is just a MIXTURE that cannot be separated
