Actually, the half-lives of most superheavy elements is measured in microseconds or nanoseconds; thirty whole SECONDS would be like forever and a day for them. Practically an eternity.
The biggest naturally element is uranium. Scientists have made new elements by merging different elements, but most of these elements just live in some seconds before they spilt again, and aren't considered as natural elements.
We weren't there; NOBODY was. There was nothing at the moment of the Big Bang, and we cannot be certain of what came into existence or when in the seconds, minutes or hours following the event. So, "immediately"? We believe - based entirely on poorly-understood mathematical theories for which no practical test is possible - that "matter", in the sense of protons, neutrons, electrons, and their corresponding antiparticles, probably did come into existence within a few seconds of the event.
Thoron is a radioactive isotope of radon, Rn 220, having a half-life of 54.5 seconds and produced by the disintegration of thorium
No, unless you have just opened the switch, then wait a few seconds before touching the elements.
Stop being lazy it would take 2 seconds to look at the periodic table and find out.
False, its considered the longest any superheavy element has existed Love, Brianne
The duration of The Riff Raff Element is 3000.0 seconds.
The duration of All Songs Considered is 2400.0 seconds.

Artificial transuranics aside (some habe half-lives of 2.4 seconds) Five seconds-out! The only naturally occurring element to have become extinct in nature was Didymium, element No. 96. More prosaically it was reclassified as two separate elements Neodymium and Praseodymium, both (Rare Earths) Dysprosioum
Element 117 was announced in January 2010, and it has a half life of around 0.078 seconds. It hasn't been studied enough for any of the properties to be determined.
A water heater element will burn out in a mater of seconds if you apply voltage to it while it is not submerged in water.
considered speed= ? considered distance= 309 meters considered time= 17 seconds therefore speed= 309/17 = 18.7 meters per second = 1122 kilometers per hour
213At (Astatine) which has a half life of 125 nanoseconds or 0.000000125 seconds.
after 3 seconds or longer=)
