Define Atom 

What is the smallest object that retains the properties of an element? 

Contains protons neutrons and electrons. 


100

The name of this atomic model. 

What is the Bowling ball model ?

100

This person discovered the electron 

Who is JJ Thompson?

200

One similarity and one difference between the quantum mechanical model and the bohr model. 

Both have energy levels associated with electrons, higher energy levels are located farther away from the nucleus of the atom

Both models allow electrons to jump energy levels and release a photon of light 


Bohr model assigns electrons orbit in fixed line, where QMM is a probability cloud. 

Quantum mechanical model is a mathematical approach.

Define Isotope 

What is two or more atoms that have the same atomic number (the same number of protons) but a different number of neutrons.

Ex: Carbon- 12 , Carbon-13, Carbon 14

Define orbital and give the shapes of the main orbitals.

What is a mathematical function describing the location and wave-like behavior of an electron in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.

s- Sphere 

P - Dumbell

d- Cloverleaf

This person discovered Neutrons 

Who is James Chadwick ?

Why can you use line spectrum like the one below to identify an element. 


Colors represent the wavelengths associated with the energy level of electrons in each element. Photons of light are emitted after electrons are excited and move energy levels.

!!!!!Daily double!!!!!

Hydrogen naturally occurs in three isotopes; Hydrogen-1, Hydrogen-2, Hydrogen-3. 

Masses 

Hydrogen-1: 1.0078 grams 

Hydrogen-2: 2.0141 grams  

Hydrogen-3: 3.0160 grams 

If you had to guess the approximate percentages of these naturally occurring isotopes based off of hydrogens average atomic mass on the periodic table, What would they be ? 

Hydrogen-1: 100% ( Technically, 99.98%) 

Hydrogen-2: 0% 

Hydrogen-3: 0%
