1/3(x-2)=2/3x - 13/3

6/3x - 6/6= 2(6)/3x - 13(6)

2x - 1 = 4x - 26

2x - 4x = 1-26

-2x = -25

x = -25/-2

??????????

Hg is an element with a very unusual property compared to its neighbours on the periodic Table. The easy bit would be to tell what that is

But the challenge: What is the three other elements which shares that property.

Regulars may know the answer, but they should know the drill. Fastest finger first, and detailed answers are the nice ones (oh, and none of this cut & Paste off Wikipedia cheating, thats Laziness, not scientific).

I ussually provide a morning wake up chance as a break for the thinkers from the mundane questions, however this unfortunately will be the last question on the morning brain workout. More details of why can be found here:-

Has anyone ever tried to kill a cat flea with a regular 9 volt battery, say like are used in a smoke detectors?

If you took about a teaspoonful of baking soda in a cup of water, wet your cat with it (assuming you cat had fleas) would a 9 volt battery just annoy the flea, paralyse it, or kill it?

I keep seeing articles saying we have to go to renewable energy sourses and soon. What options do we have. Hydro power is being used and has nearly reachedits limit. Wind power so far has not proven it's worth. It takes a huge number of wind turbines to even begin to make a dent in consumption of fossil fuels. The same with solar power. It would take a vast amount of solar cell panels just to power one factory. Bio fuels such as Bio diesel and alcohal use up a vast amount of crop land that will soon be needed to feed the growing population. Hydrogen has potential but so far it takes more energy to produce it than the energy it provides. Fusion nucular may be the best answer in the long run if it ever becomes possible to build fusion reactors that donot take outside energy to run them. Fision reactors create a vast amount of dangerous wste that will last far too long. Any one know of any alternative that can bee viable?
