The smallest building blocks of matter 

Atoms

100

Is this model an element, a compound, or a mixture?


Compound

100

These are substances that have lost electrons

Cations

100

What is the current model of the atom?

The Quantum Model or the Electron Cloud Model discovered by Schrodinger and Heisenburg. Shows us s, p, d, f electrons 

100

These are forms of same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass.

Isotopes

100

A student is analyzing an unknown sample of metal using the flame test. The student burns the unknown metal and finds it to be a bright cherry red when burned. What is the possible identity of this metal based on your own lab experience?

Possible answers: Lithium, Strontium

200

These are the three subatomic particles that make up the atom

Protons, neutrons, and electrons

  1. Describe the process depicted above. 

  2. What is the resulting atom a new element?

1. Nucleosynthesis - the fusing of two elements to produce a larger nuclei

2. Helium is produced

How many protons and electrons are in the phosphorous ion?

Protons = 15

Electrons = 18

This is why copper appears blue when burned and a diagram that depicts this phenomenon

Because as electrons fall back from an excited state to ground state, they emit light.

300

The element copper (Cu) has two naturally occurring isotopes, copper-63 (62.930 amu) and copper-65 (64.928 amu). The average atomic mass of copper listed on the periodic table is 63.55 amu. Of these two isotopes, this one is the most abundant for this reason

Copper-63 because the average atomic mass of the element is closer to its mass

What are the names of the 4 quantum numbers and what do they tell us?

n - principal quantum number - tells us the energy level of the electron

l - angular momentum quantum number - tells us the shape of the orbital the electron is in (s, p, d, f)

mL - magnetic quantum number - tells us the orientation in space of the orbital

ms - spin quantum number - tells us the spin of the electron

Who developed each of the following models and what is the limits and merits for the planetary model?

Solid Sphere - Dalton/Democrateous

Plum Pudding Model - J. J. Thompson

Nuclear Model - Rutherford

Planetary Model - Bohr

Quantum Model - Schrodinger/Heisenburg


The Bohr model finally shows us that electrons exist in orbitals (merit) but their placement isn't 100% correct (limit)
