He2 cannot exist because it has a bond order of 0. CO has no unpaired electrons in its molecular orbitals. B2 has two unpaired electrons in the π2p orbitals. NO has ... Mar 30, 2020 · Based on molecular orbital theory, He2 should not exist, and a chemical bond cannot form between the atoms. However, the van der Waals force exists between helium atoms as shown by the existence of liquid helium, and at a certain range of distances between atoms the attraction exceeds the repulsion.

- Another example is He2+ ion. There are totally three electrons with one unpaired electron and two paired electrons in He2+ ion. The paired electrons are belonging to one He atom. The one unpaired electron forms the chemical bond of the two He atom. Thus, He2+ is paramagnetic. Thus, both the bond order of H2+ and He2+ is 0.5. |
- Almost all main group compounds (ns np valence electrons) are diamagnetic. Why is [NiCl4]2- paramagnetic while [Ni(CN)4]2- is diamagnetic? * The valence shell electronic configuration of ground state Ni atom is 3d 8 4s 2 . Salt: Diamagnetic. Here, for H2 the number of unpaired electron is 0. Indicate whether F-ions are paramagnetic or diamagnetic. Diamagnetic characteristic of an atom/ion ... |

- In an experiment to determine the order with respect to H+(aq), a reaction mixture is made containing H+(aq) with a concentration of 0.500 mol dm–3 A large excess of both H 2O 2 and I – is used in this reaction mixture so that the rate equation can be simplified to rate = k 1 [H +]c. 0 1 Explain why the use of a large excess of H
The bond order calculation shows that there will be a bond order of zero for the He2 molecule--exactly what we should predict given that helium is a noble gas and does not form covalent compounds.... Dec 31, 2020 · Bond order of O 2. Electronic configuration of O. Number of bonding electrons = 8. Number of anti-bonding electrons = 4 . Bond order = 1/2 (8-4) =2. Hence, the bond order of oxygen molecule is 2. Bond order of O 2 + Electronic configuration of can be written as: Bond order of O 2 + =1/2 (8-3)= 2.5. Thus, the bond order of O 2 + is 2.5. Bond ...
Arrange the following in increasing order of bond order C2,He2,NO,O2. Arrange the following in increasing order of bond order C2,He2,NO,O2. Share. What is atom? Atom is the smallest constituent unit of matter that retains the properties of an element. A typical atom consists of a nucleus and electron cloud.Atom components are positively-charged protons and electrically neutral neutrons in the nucleus and negatively-charged electrons orbiting this nucleus.
