I went straight to a PhD after my bachelor's and I have lots of thoughts. -You get finished with your degree faster - you don't have this interim stage between BA and PhD. -You don't have to figure out how to pay for your MS, or worse, take on debt for it. -You get to jump right into what you really want to do.
What is the ionic charge of a sulfate ion? Which has a larger ionic radius a strontium ion or a rubidium ion? Both are ions and we should consider the ionic radius, not the atomic radius. Rubidium ion (Rb+) will have a larger IONIC radius than strontium ion (Sr2+). Both ions have â¦the same electronic configuration. But strontium ion has more number of protons in the nucleus. Hence it will have greater force of attraction between the nucleus and the valence electrons, resulting in smaller size.
1 Rubidium is a soft, silvery-white metallic element of the alkali metal group. 2  Its atomic mass is 85.4678. 3  Elemental rubidium is highly reactive, with properties similar to those of other elements in group 1 in the periodic table, such as very rapid oxidation in air.4  Rubidium has only one stable isotope, Rb-85.ubidium is a metallic element sited in the alkaline group on the periodic table of elements. It is used in a variety of industries, and it is also utilized in laboratories for a range of experiments. The element also has a number of radioactive isotopes which are used in research and dating of ancient fossils.
