Well, honey, let me break it down for you. 925 silver is sterling silver, which means it's 92.5% pure silver and 7.5% other metals. On the other hand, 929 silver is a bit purer at 92.9% silver. So technically, yes, 929 silver is slightly better in terms of silver content, but in reality, the difference is so minimal that most people wouldn't even notice.

2 different isotopes of uranium. isotope= element with same number of electrons, same number of protons, different numbers of neutrons. U235 has 143 neutrons and 92 protons U238 has 146 neurtons and 92 protons
235U and 238U are two different isotopes of natural uranium. 235U has 143 neutrons and 238U has 146 neutrons. The atomic mass of 235U is 235,043 929 918 ± 0,000 001 957 and the atomic mass of 238U is 238,050 788 247 ± 0,000 002 044. 235U is fissionable with thermal neutrons but 238U not; another nuclear properties are also very different; the chemical properties are the same.
