Question:

How to find out the valence electrons?

Someone explain please! And make try to make it so simple that a fith grader could understand please! Thank you so much!

Answer:

All the pro-global folks areScientists see a cashcow and jump on the band wagonThe brainless ones think because some politician made a movies and pseudo-scientists agree then it must be trueWho knows, they did save us from the iceage that was supposed to hit us about now.
No more than ADM and other corporate farmers are milking profits from producing ethanol and selling it to oil companiesI have no problem with people trying to make a positive change and making a profit from the processThat's fairMy beef is with companies that aren't doing the right thing to begin with.
You know, this story starts to make me re-think the former VPThis guy is really using the American system to its fullest in some of the finest traditions of entrepreneurshipAnd I'll say it again, the tide has turned on Global warmingThe temperatures started falling a few years ago, and more and more stories are coming out that make people shake their headsThis is another fine example
Yes he isHe is doing it to get votes for himself and the democratic partyPlus he wants to get in good with the UN and produce the worlds first UN tax on carbon emissionsHe will become a very wealthy man if that happensSay thanks to the government/media complex owned by the Clintons and all of those useful idiots out there in America who think that global warming is being caused by man.
Look at the periodic table, the version with the Roman numerals at the top of each columnThe Roman numeral tells the number of valence electronsSodium is in column IA it has 1 valence electron Aluminum is in IIIA it has three valence electrons Manganese is in VIIB it has seven valence electronsZinc is in IIB it has two valence electrons Phosphorous is in VA it has five valence electrons Chlorine is in VIIA it has seven valence electrons The A columns are the representative elements The B columns are the transition metals The valence electrons are defined as those which can take part in chemical reactionsThe valence electrons are the outermost electrons in an atomThe valence electrons are found in the energy sublevels (s, p, d and f) with the highest principal quantum number (n)Consider phosphorous, which is in group VA, and has five valence electronsThe electron configuration is 1s2, 2s2 2p6, 3s2 3p3 The outermost sublevels, that is, the ones with the highest principal quantum number (n3) are the 3s and 3p sublevels, in which there are 5 valence electrons, 2 in the 3s and 3 in the 3p.
