History of Chemistry
The names of many elements come from English and this language.
What is Latin?
This is the inner part of an atom, which contains the proton and the neutron.
What is the nucleus?
Atomic masses are measured with this unit.
What is an AMU?
This is anything that takes up space (has a mass).
What is matter?
There were many models of the atom. This one described electrons as moving in planetary orbits.
What is the Bohr Model?
These particles have a positive charge and are found inside the nucleus.
What are protons?
A proton and neutron both have this atomic mass.
How much is 1 AMU?
These are the smallest units of unique matter.
What are atoms?
Carbon's atomic number is _______.
6
This chemist discovered that atoms are made up of mostly empty space, with one part positively charged and one part negatively charged.
Who is Ernest Rutherford?
The mass number of an atom is found by doing this to the number of protons and neutrons in the atom.
