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.
-Because the charged rod doesn't touch the sphere, no charge is added to or removed from the sphere. Instead, the rod attracts some of the sphere's negative charge to the side of the sphere near the rod. This leaves a deficit of negative charge on the opposite side of the sphere, so that side is now positively charged. The negative charge on the sphere is close to the rod so it is strongly attracted to the rod. The positively charge on the sphere is far from the rod, so it is weakly repelled by the rod.
