2017年1月10日 · $\ce O$ is a free oxygen atom and $\ce{O2}$ is two oxygen atoms chemically bound to form an oxygen molecule. There is no common analogy for $\ce C$, but $\ce{N2}$ is …

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 …

2023年2月18日 · O2-: Two electrons are added there is more inter-electronic repulsion, so the radius increases (and it is more than F-, because here two electrons are added but in F- only …

2019年7月5日 · The size of an anion is greater compared to its parent atom because former's effective nuclear charge is lesser than that of latter. I found on wikipedia that the effective …

Since an oxygen atom has 6 electrons, A would correspond to a structure with a single bond between the oxygen atoms, 2 lone pairs on each oxygen and an unpaired electron on each …

2018年2月25日 · Well, it depends on other factors as well... We cannot find the definite volume given your conditions, as the volume also depends on the pressure and the temperature. …

2017年5月30日 · $\begingroup$ The 2 O represents two separate oxygen atoms, ( not connected to one another so free to move around and react independently ), the $\ce{O2}$ is molecular …

2018年11月25日 · 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 course. …

2016年7月5日 · O_2 is actually a molecule of oxygen. Oxygen is one of the diatomic molecules formed by covalent molecules allowing the electrons of the element to pair and stabilize the …

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 …
