Worksheets

With this blog we did book work about Quantum Mechanics. Quantum Mechanics states that only a certain amount of electrons can be in a shell. The number increases as you continue out from the nucleus. With the first shell it can only hold two electrons, the second shell has eight, the third shell has 18. The levels or shells are also called orbitals. These orbitals have sub-levels starting after the first orbital. Each level starts with the S orbital. The S orbital holds two electrons. When the orbital is filled, you start to fill the sub-levels. The first sub-level is the P. Did you know you can name elements by their orbitals.  An example of electron configurations is Bromine (Br) Bromine has 35 electrons: [Ar]4s23d104p5.

Standard 8

Remebering: What I did in chemistry is
1. Properties of matter blog
2.  Separation Techniques Lab
3. Light and Atoms Review
4.Introduction to Electron Configurations in Atoms

What is important about it:
Each blog was interesting to write and learn whats new in the world of chemistry and just a new insight of the world of chemistry.

Applying:
 I could apply this in everyday life. Well I want to become a nurse so I think I could use this when I go to medical school.

Evaluating:
How I did this 1st quarter I think I did well I kept up with my blogs and kept a steady standard of proficent. So I would say that I did very well for my very first time being in Mr. Ludwigs class.

Creating:
Next quarter I could put some youtube videos, websites, and just more visual effects to my blogs to give a further explanition of what we are studing.

Light

Did you know that light is a type of electromagnetic radiation? Electromagnetic radiation is a kind of energy and acts like a wave as it travels through a space. (Examples of that incule X ryas, Radio waves, and Microwaves. ) Waves can be characterized by their wavelength, amplitude, frequency, and speed. The shortest distance between equivalent points on a continuous wave is called a wavelength. The height of a wave from the origin to a crest or from the origin to a trough is the aptitude.  Frequency is the number of waves that pass a given point in one second. The SI unit for frequency is Hertz which is the same to one wave per second.
With this diagram you can see what a wavelength, frequency, and what amplitude is and what the symbol is for wavelength.




 I looked through a spectroscope at 9 different lights.. The lights we looked at through the spectra scope are in order from the longest wave length color with the highest frequency (red), then the colors become shorter- orange, yellow, green, blue, indigo, and violet. Violet has the shortest wave length with the lowest friquency. Also with every light we observed it gave off a gas and the gas that I observed had a different spectra for each light. 

My lab with the spectrum and diffrent lights. With the lab is a scale the scale is what was inside the spectrascope the wavelength the higher the number the longer the wavelength and the higher the frequency.

Atomic Structure

Atomic Structure

We should first understand the models of elements we have Daltons atomic theory that explains the all matter is small and the particles are called atoms.












The second is J.J. Thomson's plum pudding model that proposed that negatively charged elections were distributed throughout a uniform positive charge.















The last is Ernest Rutherford. He expected most of the fast moving and relatively massive alpha particles to pass straight through gold foil. He also expected a few of the alpha particles to be slightly deflected by the electron in the gold atoms.















Remember back in elementary school when we were first learning about atoms and they told you about neutrons being neutral, protons being positive and electrons being negative. Yes that is true but now we go even more in depth of that. Now we learned about Isotopes and atomic mass. Crazy to think that such a little thing has a lot of depth to it.


         Everything that is needed to known about an atom is on the periodic table of elements. At the beginning of the table you have an element broken down  like this chlorine element.





You have protons and neutrons in the nucleus of an atom and the electrons are floating around the nucleus of the atom.

The final steps to understand an atom are as followed:

  • You look at the atomic number and the the atomic number is the same number of protons and electrons.
  • Mass number is the average of all isotopes of the element.
  • To find neurons you subtract the Atomic number form the atomic mass
So understanding atomic structure isn't as hard as it sounds.
