The word atoms comes from the greek atomos which means this.
What is indivisible
This subatomic particle is negatively charged and has almost no mass but accounts for most of the space of an atom.
What is an electron
This color light has the longest wavelength
Red
An explanation that has been repeatedly supported by many experiments.
What is a Theory
A neutral atom of Iodide has this many electrons.
What is 53?
The smallest particle of an element that retains the properties of the element.
What is an atom.
These two subatomic particles are found in the nucleus.
What are protons and neutrons
The shortest distance between equivalent points on a continuous wave
What is wavelength
J.J. Thomson studied cathode ray tubes and discovered the atom was divisible, he discovered this subatomic particle
What is an electron
1s22s22p3
What is the electronic configuration for Nitrogen?
This is a model/analogy to describe JJ Thomson's version of the atom
What is Plum pudding/Blueberry muffin/chocolate chip cookie
What are protons and neutrons
This type of electromagnetic radiation is routinely use to quickly warm up food.
What are microwaves
In this famous experiment Rutherford observed the behavior of alpha particles and discovered that atoms have a small dense nucleus.
What is the Gold Foil Experiement
The electron configuration for Germanium
What is 1s22s22p63s23p64s23d104p2
Rutherford's nuclear model added this feature to the atomic model
What is the nucleus
The number of this subatomic particle determines what element it is.
What is the proton
Of the two, ultraviolet and infrared, this one has the highest energy.
What is Ultraviolet
The feature of an atom that was discovered by Rutherford and the gold foil experiment.
What is the nucleus
The noble gas configuration for Cs
What is [Xe]6s1
In the quantum mechanical model this is a 3D region around the nucleus that represents the probable location an electron.
What is an atomic orbital
The number of neutrons in Carbon-13
What is 7
As the wavelength of electromagnetic radiation gets shorter the energy of the radiation does this.
What is increases
Bohr used this evidence to support his claim that electrons move around the nucleus in only certain allowed circular orbits.
What is hydrogen's atomic emission spectrum
What is the Aufbau principle AKA bottom up AKA electrons fill subshells of the lowest energy first.
