Explanation:
1) The dots in Lewis Notation represent the Electronic Valence, in other words, the amount of Valence Electrons. The Lewis structures has the advantage of pictorially displaying the valence electrons around the symbol of the Atom.
2) We can easily find in a Periodic Table the number of bonds. Notice that we must rearrange the dots to observe the rule of the Octets. Each atom tends to have more stability and behave as noble gas, with eight electrons in its outer shell. So, in some examples, we'll have to rearrange the dots in order to have follow the <em>Octet rule</em>.

Answer:
REFRACTION IS THE BENDING OF A WAVE AS IT PASSES AT AN ANGLE FROM ONE MEDIUM TO ANOTHER. WHEN A WAVE MOVES FROM ONE MEDIUM TO ANOTHER, THE WAVE'S SPEED CHANGES. WHEN A WAVE ENTERS A NEW MEDIUM AT AN ANGLE, THE PART OF THE WAVE THAT ENTERS FIRST BEGINS TRAVELING AT A DIFFERENT SPEED FROM THE REST OF THE WAVE.
Explanation:
During feasting, there is an increase in the supply of carbohydrates, fats and proteins in the body. Since these macronutrients are in excess, carbohydrates and proteins are utilized or oxidized as a source for energy production. On the otherhand, fats are accumulated as the rate of oxidation of this source does not increase during feasting.
Answer:Explanation:The higher the frequency, the faster the oscillations and thus the higher the energy. Therefore, the highest-frequency ultra-violet light (or the lowest wavelength) is violet. However, the highest-frequency visible light would have to be roughly blue.
