Let’s use an example to decipher this chemistry puzzle. Carbon and hydrogen are like the best buddies of the periodic table. In methane (CH4), carbon has an oxidation number of -4, while hydrogen has an oxidation number of +1. This tells us that carbon is eager to share its electrons, making it a good electron donor. Hydrogen, on the other hand, is a little greedy and wants to accept electrons. So, these two elements form a stable and happy molecule, coexisting in perfect balance.
Now, let’s introduce nitrogen, the wildcard of the trio. In ammonia (NH3), nitrogen has an oxidation number of -3. It’s not as desperate for electrons as carbon, but it’s still willing to share. Hydrogen, ever the electron hoarder, has an oxidation number of +1 again. However, this time, there’s a slight mismatch. Nitrogen isn’t as generous as carbon, so the electrons tend to linger a bit more around hydrogen. This subtle difference in oxidation numbers creates a polarity in the molecule, making ammonia a great solvent.
Understanding oxidation numbers is like having a secret weapon in your chemistry arsenal. It helps us predict the stability, reactivity, and bonding patterns of compounds. So, the next time you encounter a chemical formula, don’t just look at the symbols; delve into the hidden world of oxidation numbers to unlock its true meaning.

Chemical formulas are like the addresses of elements in the molecular world. They tell us the elements that make up a compound and the exact number of atoms of each element that are hanging out together. And in the Criss Cross Method, these addresses are pure gold.
How it Works:
Imagine two elements, like sodium and chlorine. When they meet, they have this undeniable attraction for each other, like magnets. The Criss Cross Method uses their chemical formula, NaCl, to calculate their closeness rating. The sodium atom loses an electron, becoming a positive ion, while the chlorine atom gains an electron, becoming a negative ion. The opposite charges attract each other, creating a strong ionic bond.
The Magic Number:
The closeness rating in the Criss Cross Method is a measure of how strong this bond is. It’s calculated by adding up the oxidation numbers of the ions and taking their absolute value. In the case of NaCl, sodium’s oxidation number is +1, and chlorine’s is -1, so the closeness rating is 1.
The Higher the Rating, the Closer the Bond
The higher the closeness rating, the stronger the bond between the elements. That means sodium and chlorine are practically inseparable, like the yin to each other’s yang. And this applies not only to ionic compounds like NaCl but also to covalent compounds like water (H2O) and even organic molecules like methane (CH4).
So there you have it, the power of chemical formulas in the Criss Cross Method. They unlock the secrets of closeness between elements, revealing the intricate dance that makes up our chemical world. And who knows, maybe next time you look at a chemical formula, you’ll see not just a string of letters and numbers, but a story of love and attraction that’s written in the stars.
