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.
Mg has 12 protons in its nucleus - these are positively charged Surrounding the nucleus are 12 negatively charged electrons. Because the number of positive charges matches the negative charges, the atom is overall neutral The neutral atom can lose 2 electrons from its outer shell. This leaves 12 positively charged protons, and only 10 negative charged electrons The magnesium ion has 10 electrons and a charge of 2+ . The Mg atom - like all atoms - does not lose protons from the nucleus, in the chemistry that you are studying. It can only lose or gain electrons.
