1. Describe Schrodinger and Heisenberg models of the atom.
Schrodinger proposed that electrons were placed in wrapping waves around the atomic structures.That they were in fact, part of these waves, rather than individual, minuscule particles placed around the nucleus.  

Heisenberg combined the atomic models of Schrodinger and one other atomic scientist. Discovering that the electrons were placed in orbiting rings as Schrodinger thought, but that there were, in fact, small particles within them, that were actually called electrons.  


1. Describe light in terms of frequency, wavelength, and energy. (Include all 7 types of waves).
Light is produced in 7 different types of electromagnetic activity. The first, slowest, lowest frequency and longest wavelength is the radio wave. These are typically used for televisions, and other short distance electronic endeavors. Next, is the microwave. These are slightly smaller, and higher in frequency than the radio waves. These are used for, you guessed it, microwaves, as well as speed cameras. Infrared light has an even smaller wavelength, and are placed immediately next to visible light waves. 


1. What are the photoelectric effect and emission spectra? (It’s the rainbow poster in my room. You may look up this information).
If a light, with a high enough intensity, is shown onto a piece of metal, electrons will be emitted from the metal itself. The energy with which the electron is removed from the substance will depend on the energy of the light. Meaning, the higher the energy within the light is, the electron will be ejected more forcefully. 


1. Write the electron configuration for Antimony.
Atomic number: 51
Number of Protons: 51
Number of Neutrons: 71
Number of Electrons: 51
Electron Configuration: 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4d⁶, 5s², 4d¹⁰, 5p³


1. Write the noble gas configuration for Antimony.

[Kr] 5s², 4d¹⁰, 4f³ 


1. Draw the orbital diagram (once again, yes draw this one, not find an image on Google).

Antimony (Sb) Block electron diagram drawing.

1. Honors Chem: What are the quantum numbers for antimony? Describe what n, l, m, and s represent.  
n = 5 
l = 1
m = 1
s = +1/2 

n - Represents the energy level placement within the periodic table. 

l - Represents the shape of which the electron creates with its orbital rotation. 

m - represents the order the electrons are placed in with relation to one another within the orbitals. 

s - Represents the either negative, (backward) or positive, (forwards) spin of the electrons. 


1. Describe how you can tell what element this is from the image below and give the correct full electron configuration.



(source) periodictable.com Sulfur information. 




The element shown in the image is Sulfur due to the presence of 4 valence electrons in the picture. Because each arrow represents an electron, there are shown to be 16 electrons in the different, collective, orbitals. This proves it as Sulfur yet again, as it contains 16 electrons.
