The strong nuclear interaction ultimately boils down to the forces between the "colorful" quarks inside the protons . It is one of eight elements named in honour of celestial objects, but you might not think that uranium deserves to be named after the planet Uranus. to choose an initial position so that the strength of the interaction between the particle and the nucleus ( the coulomb force ) is much smaller than it will be when the two are very close. Kathryn has taught high school or university mathematics for over 10 years. In n = 1 shell, electrons are at the closest possible distribution to the nucleus. It is defined as being the charge that an atom would have if all bonds were ionic. Previous Tries Your receipt no. Wondering how many helium balloons it would take to lift you up in the air? The reputation of this element would also be significantly better if only uranium glass was the element's most publicly known face. This is 40 % less radioactive than natural uranium, and the material that we use to make compounds from in the lab. Melting point Atoms consist of electrons A subatomic particle with a negative charge that resides around the nucleus of all atoms., .

Because it is so dense, DU is also used in shielding, in the keels of boats and more controversially, in the noses of armour-piercing weapons. Critics of DU weaponry claim it can accumulate around battlefields. However, the uranium nucleus is far from spherical, and its imprecisely determined shape causes uncertainties in the computations.
