What happened to the molecule when the electron was promoted to the antibonding orbital?.
____ [38]

the bond will break

The bond will dissolve (break) if the electron absorbs a photon and is moved from a bonding molecular orbital to an antibonding orbital since there is no longer an overall stabilizing interaction.

<h3>What is an antibonding orbital?</h3>

An antibonding molecular orbital is the molecular orbital created by the destructive overlapping of atomic orbitals.

<h3>Why is it called antibonding orbital?</h3>
  • Every atom will add one electron to the bond that makes up the lower energy bond.
  • To prevent interacting with the other two electrons, the additional electron will occupy a higher energy state.
  • The antibonding orbital is the name of this higher energy orbital.

<h3>What orbitals form an antibond?</h3>
  • The bonding orbitals are home to electrons that spend the majority of their time between the nuclei of two atoms, whereas the antibonding orbitals are home to electrons that spend the majority of their time outside the nuclei of two atoms.

<h3>When an electron was elevated to the antibonding orbital, what happened?</h3>
  • In contrast, putting electrons in antibonding orbitals will make the molecule less stable.
  • The energy levels of the orbitals will determine how many electrons are filled.
  • The lower energy orbitals will be filled first, and then the higher energy orbitals.

Can u guys help on 22. It will only take a min.
Anni [7]

Answer:

Alpha > beta>gamma

Explanation:

Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

In a compound with molecular formula X2Y3, the valencies of Y and X are
Kaylis [27]

Answer: In a compound with molecular formula X_2Y_3 ,the valency of Y and X are 2 and 3 respectively.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.  

The given compound is X_2Y_3 where X and Y combine and their oxidation states or valencies are exchanged and written in simplest whole number ratios. Thus the oxidation state or valency of X is 3 and that of Y is 2.
