In electrically neutral atoms, how many (a) protons are in the uranium $\frac{238}{92} \mathrm{U}$ nucleus, (b) neutrons are in the mercury $202 \mathrm{Hg}$ nucleus, and (c) electrons are in orbit about the niobium 93 $\mathrm{Nb}$ nucleus? $41^{?} ?$
Which (if any) of the following can be determined by knowing the number of protons in a neutral element? Explain your answer. a. the number of neutrons in the neutral element b. the number of electrons in the neutral element c. the name of the element
In each case, identify the element in question. (a) The mass number of an atom is $234,$ and the atom has $60.0 \%$ more neutrons than protons. (b) An ion with a +2 charge has $10.0 \%$ more protons than electrons. (c) An ion with a mass number of 110 and a $2+$ charge has $25.0 \%$ more neutrons than electrons.
