Fundamental Forces
This force is trying to pull you down into the Earth
What is gravity
The "plum pudding" model was created after the discovery of this negatively-charged particle
What is the electron
This positively charged particle is found in the nucleus
What is the proton
Protons and neutrons are almost the exact same, in this measurement
What is mass
A substance made of only one type of atom, chemically speaking
The repulsion from this force keep atoms from passing through each other
What is electric force
This phrase is what Democritus meant when he first called an imaginary particle "atom"
What is un-cuttable or indivisible
The electron is NOT found in this location of the atom
What is the nucleus
Protons and electrons share this exact quantity, but in opposite directions
What is charge
A change in the number of these particles will change the chemical identity (or element) of an atom
What is a proton
Electric force would cause two negative charges to do this
What is push or repel
The Rutherford experiment led to a model that shows the atom as mostly this, volume-wise
What is empty space
This subatomic particle does not interact with the electric force
What is the neutron
Light waves have this quantity of mass, and of charge
What is zero
A change in the number of these particles will turn a neutral atom into an ion of the same element
What is an electron
The electric force would cause a negative charge and a positive charge to do this
What is pull or attract
The Bohr model of the atom differs from the Rutherford model by the inclusion of theses specific and predictable energy levels
What are orbitals
The lowest energy state can hold this number of electrons in it
What is 2
When two atoms share a pair of electrons, they create one of these
What is a chemical bond
A change in the number of these particles will create a different isotope of the same element
What is a neutron
This is the strongest fundamental force, strong enough to keep protons stuck together.
What is the strong nuclear force
The Schrodinger model shows electrons as these, instead of as particles
What are waves
Going even smaller: protons and neutrons are made of this type of particle
What is a quark or gluon
When light interacts with an atom, it allows this thing to be absorbed or released
What is energy
This cone-shaped flask is good for mixing liquid chemicals by swirling from the neck
What is an Erlenmeyer flask
