Models / Old guys
This is the name for JJ Thompson's atomic model.
What is the plum-pudding?
These are the small particles on the outer-most shell of the atom.
What is a valence electron?
These elements have 8 valence electrons and don't normally bond.
What are noble gases / inert gases?
The element has an atomic number of 7
What is Nitrogen?
He discovered that atoms have a small, dense nucleus.
Who is Rutherford?
These two subatomic particles have the same mass
What are protons and neutrons?
Different groups of the periodic table tend to have different numbers of this
What are valence electrons?
These 2 elements have 29 protons and 82 protons respectively
What are Copper and Lead?
This is where electrons can be found in the modern model
What are electron orbits / shells?
This is the formula to calculate the number of neutrons in an atom.
What is Atomic Mass – Atomic Number?
This family of the periodic table has the most reactive metals.
What are the Alkali metals (Group 1)?
This atom has 86 electrons
What is Radon?
This is the pattern of the electrons allowed on the first 3 shells. (hint: Argon's electron configuration)
What is 2, 8, 8
This is the number of electrons that would be in the 3rd energy level of sodium. (electron configuration)
What is 1?
Changing the amount of this particle will create a new isotope of the same element
What is a neutron?
Which elements are around the staircase line?
What are metalloids?
The element with the symbol Ru, has this many protons
What is Ruthenium? (Ru)
This is the model we have used most often in this class, where electrons are found at different energy shells
What is the Bohr model?
According to its atomic mass, this is the most common isotope of oxygen
What is oxygen-16 (O-16)
This is the heaviest element on the periodic table
What is Oganesson? (Og)
These atoms have the following number of electrons: 88, 22, and 66
What is Radium (Ra), Titanium(Ti), and Dysprosium (Dy)?
