Quick science question.?

Answer:

You need a periodic tableAl is number 13, meaning it has 13 protons (positive charge) so in a neutral atom of Al, it will have 13 electronsElectrons are located in orbital shellsThere are s, p, d and f levels (there are more but these are the most common)The order is first energy level1s, second energy level 2s 2p, third energy level 3s, 3p, 3d, etcThe s level has 2 e- (electrons), p level has 6e-, d has 10 e- and moreBack to Al: 1s has 2e- 2s has 2 e-, 2p has 6 e- 3s has 2 e- and 1 e- for a total of 13 electrons and the highest energy level is in the 3rd orbitalTo draw it, just draw Al in a small circleThen draw circle for 1st, 2nd 3rd energy levelDraw 2 e- in the 1st, 8 e- in the 2nd and 3e- in the third (outermost shell)If you were to write itJust write Al and then draw 3 x's to represent the 3 e- in the outermost shell Since atoms like the octet rule (8 electrons), elements will combine with others, take or give away there electrons to fill the octet ruleAluminum has 3 e- in it's outershell so it likes to give away the 3 e-Normally you will find Al as a postively charged ion or Al 3+ signifying a postive charge of 3I hope this helps somewhatI'm sure you can google this info.
I checked at a Hoover Dam (not damn) site that said a tower crane fell over on Friday, closing the road in both directionsThe road is now re-opened, as of Monday night 8pm.
If it is closed to tourists, it is usually because of some kind of security riskThat happens with a fair degree of regularityIf terrorists take out Hoover Dam, the whole west coast is largely without electricity.
Because if it wasn't the water would run out of Lake Mead.
probably to not take chances of a terrorist attack.Last time i went through there they were searching cars.
