Atomic Structure
What does it mean to be a vanilla atom?
#p = #n = #e
The first thought experiment of an atom was with this item...
Cheese
If an element has 12 protons, how many neutrons and electrons does it have?
#n = 12
#e = 12
What is the name of the model that had the first nucleus?
Nuclear Model
Which particle is unique for every element?
The Proton
What does the amount of protons and neutron make up?
Mass number
If the mass number of an element is 30, how many electrons does it have?
15 electrons
What makes the planetary model different from the nuclear model?
In the planetary model, electrons are at specific energy levels around the nucleus. The Nuclear model just showed electrons in the empty space around the nucleus.
If the mass number of an element is 100, how many protons, neutrons, and electrons does it have?
50 protons, neutrons, electrons
What is the net charge of a vanilla atom? How do you know?
0 because the number of protons equals the number of electrons
What is the atomic notation for Sulfur if it has an atomic number of 16?
Ms. Correa knows
Which model was the first to be discovered using experimental data?
The solid ball
What is the name of the model that first discovered electrons?
Plum Pudding Model
Where are protons and neutrons found? Where are electrons found?
Protons and neutrons are in the nucleus. Electrons orbit the empty space around the nucleus.
What is the atomic notation for Iodine if it has 53 electrons?
Ms. Correa knows
Briefly explain the Gold Foil Apparatus and how the data connects to the Nuclear Model.
The data for the Gold Foil Apparatus showed that alpha particles bounced back towards the opening, which showed us that there was a dense positive center in the atom along with empty space.
Put the names of the 5 models in order from when they were discovered.
Atomos
Solid Ball
Plum Pudding
Nuclear
Planetary
