Why do we call O2 oxygen? - Chemistry Stack Exchange
2018年11月25日 · 1. Diamond and graphite are both arrangements of carbon atoms, each with very different properties and yet they are both pure carbon, as is a single carbon atom, of …
Why is the first ionization enthalpy of molecular O2 less than …
2020年9月17日 · According to the MO diagrams, the bond order of $\ce{O2}$ is 2 and that of the cation $\ce{O2+}$ is 2.5 (after all, we are removing an antibonding electron). Indeed, the bond …
What is the ground state electron configuration for - Socratic
2016年10月26日 · Based on the periodic table, "O" is atomic number 8, which means it has 8 electrons. The first few atomic orbitals are 1s, 2s, and 2p. Each orbital can hold 2 electrons …
What is the difference between an element and an atom?
2015年9月5日 · An atom is a thing; an element is a type of thing. An atom is a collection of protons, neutrons and electrons. A single, isolated atom in its neutral state has some number …
Why does oxygen form an O^(2-) ion and not an O^(3-) ion
2018年6月8日 · The electron configuration of "O"^ (2-) ensure the atom an octet and therefore high chemical stability whereas "O"^ (3-) doesn't. Ground-state oxygen atoms have electron …
Effective nuclear charge of oxygen atom (O) vs oxygen anion (O2-)
2019年7月5日 · I found on wikipedia that the effective nuclear charge can be calculated by the formula: Zeffective = No. of protons in the nucleus - No. of non-valence electrons. For oxygen …
