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.
The rule for an ion with a charge of +2 or -2 -- a divalent ion -- is: 1 milliequivalent of a divalent ion is equal to 0.5 millimole of that ion. A sulfate ion has a charge of -2. If you have 20 mmol of sulfate ion, use the conversion factor divalent ion to set up the following calculation:onovalent Ion Example. The rule for an ion with a charge of +1 or -1 -- a monovalent ion -- is: 1 milliequivalent of a monovalent ion is equal to 1 millimole of that ion. A chlorine ion has a charge of -1.
