Question

Imagine that you have discovered a new element in the soil of Mars called Marsantium (Ms). Martian elements have slightly different properties than elements found on Earth – full valence shells have 16 electrons rather than 2 or 8. Ms contains 15 electrons in its valence shell. (Assume that the laws of physics still apply on Mars.)

1. Is Ms likely to be reactive (form bonds with other atoms)? Why or why not?

2. You mix Ms together with another Martian element, Alenium (Am). Alenium has a valence shell with 1 electron. What type of bond is most likely to form between these two atoms? In your answer, describe how the electrons are shared or gained/lost.

Answer 1

Answer:

Martian (Ms) containes 15 electrons in its valency shell.

But this element can accommodate 16 electrons in its valency shell. Then it gaininig the electron gets a neutral and stable configuration.

1) Answer:

Martian (Ms) is good reactive atom. To get the stable electron configuration it under goes the reaction and forms as a Anion (Ms^-).

It involves in the Ionic reactions like First group elements in the periodic table.

2) Anaswer:

Ionic reaction takes place between Ms and Am. One can lose the electron and other one will gain the electron.

Alenium (Am) is having the one electron in the valency shell. Losing of the electron will gets the stable electron configuration and it forms as a Cation(Am⁺)

The Ionic reactions:

Am    Am⁺ + e^-

Ms + e^- Ms^-

Net reaction:

Am⁺ + Ms^-  AmMs

Note:

Between the two Ms atoms metallic bond takes place. It is a type of chemical bond. In this bond the electrostatic attraction takes place between the positively charged metal ions and delocalized electrons of the other metal atom.
