WebAs you can see, oxygen has eight electrons. In fact, the oxygen atom has six valence and two core electrons. The number of valence and core electrons in an atom is equal to the number of principal groups in the atom. Moreover, each element has a different number of neutrons and protons. WebThe ‘17’ in O17 represents the mass number of that isotope of oxygen. “Mass number” is the sum of the number of protons and neutrons present in its atomic nucleus. In this case, the …
How many valence electrons are in the electron _ ion?… - SolvedLib
WebThis means that oxygen has 8 protons and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8). To get the number of valence electrons just look at the … WebEach shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.[1] cinderford to lydney bus times
4.7: Isotopes and Mass Numbers - Chemistry LibreTexts
WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds. WebApr 30, 2016 · The isotope oxygen-17 has 8 protons and electrons and 9 neutrons.
