The electron cloud is split up in 3 areas.
1) Inner Electron Cloud
2) Outer Electron Cloud
3) Valence Electrons
Your inner cloud is the electrons CLOSEST to the nucleus.
Your outer cloud is the electrons in the MIDDLE of the Inner and Valence.
Your valence electrons are the OUTER LAYER of electrons. These electrons are important to bonding, and also are what decide where on the periodic table of elements. For example:
197
Au
79
This element is GOLD. It has 1 valence, therefor it is where it is in the period. Ionization could change this number however.
Wave speed = frequency * wavelength
Input the numbers into this equation :
Wave speed = 200 * 3
Work it out and you will get the answer :
Wave speed = 600 m/s
Answer:
The correct answer will be "0.25 sec".
