WebRadium is present at very low concentrations in sea water. Most radium, 226 Ra, arises from the decay of the plentiful 238 U, hence radium is obtained in residues taken from uranium production. Isotopes: Radium has 33 isotopes whose half-lives are known, with mass numbers 202 to 234. None is stable. 226 Ra has the longest half-life of 1602 years. WebEvery subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals.
