Write a short story between two/three or four elements forming a covalent compound in order to attain stability.
plz write a short story or just give me some pointers/ideas as i don't have much time left before i submit it...
if u want to know anything ask as a comment rather than posting it as an answer!!!

Answer:
BH3 atom
BH3 atom
In general, achieving the octet configuration (i.e. 8 electrons in the outermost shell) is the driving force for chemical bonding between atoms. Take a look at the outer shell configuration (i.e. number of valence electrons) of three atoms – sodium (Na), chlorine (Cl) and neon (Ne):

Ionic and covalent bonds
Let’s look at the following two scenarios A and B. There are two kids, Emily and Sarah. They both are very good friends.
Scenario A:

Scenario B:

Now let’s apply the above analogy to chemical bonding. Assume that Emily and Sarah represent two atoms, and the blanket symbolizes their valence electrons. In scenario A, atom Emily is willing to donate her electrons (blanket) to atom Sarah because by doing so both achieve an octet configuration of 8 electrons in their respective outer shells, making them both happy and stable. This donation of electrons is called ionic bonding.

In scenario B, both the atoms Emily and Sarah are equally electronegative. So, neither Emily nor Sarah is ready to part with her electrons (blanket), and they instead share their valence electrons with each other. This is called a covalent bond. Electronegativity is a measure of how strongly an atom attracts electrons from another atom in a chemical bond and this value is governed by where the particular atom is located in the periodic table (francium is the least electronegative element while fluorine is the most electronegative).
