THE ATOM
In 1910 Rutherford discovered the atom is mostly empty space but small, dense, and positively charged nucleus with the negative electrons buzzing around the outside. Unlike the model to the right, we now know that electrons do not travel in fixed orbits. Instead, we know that electrons travel in regions called clouds.
Move your mouse over different parts of the atom to gain more information.
Who was the scientist that discovered the atom was mostly empty space?

Atomic info
Use the periodic table to find the correct atomic particles found in the element.

Atomic mass
Next
The atomic mass of an atom is equal to the protons + __________.
one word, plural
Let's review:
Atomic number = protons protons (+) = electrons (-) in a neutral state Therefore: atomic number = protons = electrons What about the other number on the periodic table?
Atomic mass = nucleus nucleus = protons + neutrons To figure out the neutrons: Mass number (protons + neutrons)- Atomic number (protons)
Next
To find the neutrons you subtract the mass number and the _ _.
