U-238 is not fissionable.
Yes. In most cases the government splits the estate in half and gives half to the spouse and half to the children.
Half-life refers to nuclear isotopes. Each isotope, whether naturally ocurring or man-made, has a different half-life. You must say which element that is emitting radiationyou are asking about.
Neutrons in the nucleus of the element's atoms. It is the number of protons in the nucleus that determines what the element is. It is the total of neutrons and protons in the nucleus that gives the isotope number. Uranium generally comes in two isotopes, U235 and U238. All uranium is radioactive -- that is, it will decay into other elements over time. U238 is much more common and is very long lived radioactively and is not explosive and cannot be made into atomic bombs. U235 is much rarer, but is highly radioactive and can be made into atomic bombs. The two isotopes are mixed together at the atomic level. This is what Iran is trying to do now in it's efforts to concentrate enough U235 to make a bomb -- the process is called "enrichment."
Half of 93 is 46.5 or 46 and a half.
Far more than half of the number of the 'periodic table elements' are metals.
No, joliotium is not a man-made element. It is not a recognized element in the periodic table.
The element neon is a pure element made of only neutrons, electrons, and protons.

Beowulf fights Grendel's mother, and kills her. He kills her with a sword that was made by giants, and he splits her into two.
Mica is made up of sheets of silicate
The only split that can't be made is the third ball thrown in the tenth frame, to which the frame is completed and a spare can not be attempted. Any other time, all pin combination of splits can be picked up for a spare.
Actinium is a natural chemical element, it is not a man-made element.
