Yes, it is true.
NO!!!! Hydrogen has only ONE(1) electron Uranium has NINETY TWO(92) electrons.
Oxygen.
No. Hydrogen has 1 electron. Uranium has 92.
yes
Yes, the density of hydrogen gas is lower than that of uranium hexafluoride gas. Hydrogen gas is one of the lightest elements, while uranium hexafluoride gas is much denser due to the heavy uranium atom.
No, Uranium has far more electrons. In a neutral atom number of electrons=number of protons=atomic number. Hydrogen has 1 electron. Uranium has 92.
Yes a football is heaver than a soccer ball.
A mole of hydrogen contains Avogadro's number of hydrogen atoms, while a mole of uranium contains Avogadro's number of uranium atoms. Hydrogen is a light element with a low atomic weight, while uranium is a heavy element with a high atomic weight. This means that a mole of hydrogen weighs much less than a mole of uranium.
no
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
no...not at all
