Answer to Question #177782 in Physical Chemistry for Ananya

Question

This well-preserved, ancient asteroid, known as Bennu, is currently more than 200 million miles (321 million kilometers) from Earth. Imagine, you are in the NASA team inspecting the material of Bennu. You have figured out that the material has 5 orbit and its 4th orbit contains 13 electrons. Also, you have figured out that it can donate one electron and can bind with an earth element and after the bonding the compound is soluble in water. During the reaction process this material become activated and you can see an energy graph like this.

1. Write down the electron configuration of the atom.Does it follow the normal Aufbau Principle? Why?

2.Write down the electron configuration of the atom when it is in its charged state as stated above..

3.Write down 4 quantum numbers for the electron/s present in its 5th shell.

4. What kind of bond will be formed due to the reaction with the earth element? Explain. Why the compound became soluble? Can it make covalent bond in any way?

Answer 1

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶

The aufbau principle, from the German Aufbauprinzip (building-up principle), also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.

• ionic bond: An attraction between two ions used to create an ionic compound. This attraction usually forms between a metal and a non-metal.
• covalent bond: An interaction between two atoms, which involves the sharing of one or more electrons to help each atom satisfy the octet rule. This interaction typically forms between two non-metals.
• intramolecular: Refers to interactions within a molecule.
• intermolecular forces: Refers to interactions between two or more molecules.
