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.
For example, a neutral atom of fluorine, F, has 9 protons and 9 electrons. Because the positive and negative charges balance, it can be said that a fluorine atom has a zero net charge. It is possible for a neutral atom to lose or gain one or more electrons. In this case, the atom becomes charged and is called an ion. In the case of fluorine, it can gain one electron. Since an electron is a negatively charged species, it will have one more negative charge than positive charge, and therefore the charge on fluorine will be -1. Cations. A cation is a positively charged ion. Therefore, it is formed when a neutral atom loses one or more electrons. This is because the ion will have more positively charged protons than negatively charged electrons upon the loss of electron(s). An example of a cation is sodium after losing one electron.
