Some old drawings I did between high school and college

-some bacteria trading DNA plasmids like emails

-a walking atom bomb (his thought cloud is just a mushroom cloud lol)

-early versions of the space characters, plus the moisture probe!

-all my periodic table characters in one drawing

-the star Rigel wielding Orion’s sword and shield (I’m glad I stopped giving stars buff arms and legs)

The moisture probe is the guy on the upper left of the space characters drawing. He was a minor character I had for a while who was a space probe designed to seek out planets with warm, liquid water oceans

Gold/Aurum, Atomic no. 79, Au

Their special colour, inert and soft properties make it to be one of the important metals among human history, mainly for decoration and currency (still being a good investment today btw)

Its inertness is somehow due to special relativity and the poor shielding of the f orbital, leaving the s orbital more attracted into the nucleus, therefore making the valence electron less likely to be give away for reaction.

And for its special yellowish colour unlike other metals, is also due to the properties mentioned above, as this affected the energy gap of the electron to be smaller, gold is likely to absorb more light from the visible light spectrum (mainly blue), so the outcome reflection of light has less blue light to make it look silvery/white, making it more prone to yellow, and earn its "golden" legend.

All of the above is only from my memory and pls be noted that I maybe wrong (but it at least should be related)

Two beautiful chemical ladies on the beach 💅❤️

This is Antoine Lavoisier. He was a French nobleman and chemist in the 18th century. Born in 1743 to an attorney of the Parlement of Paris. He inherited a sizable fortune at a young age when his mother passed away. He was a stinking little genius who started at the University of Paris when he was just 11 years old. There he studied many sciences including chemistry and botany. He even got a bachelor's degree in law and was admitted to the bar but never practiced as a lawyer. He preferred to study science.

One of the super cool things he did was make the first geologic map of France in 1769.

He also wrote a paper on the chemical and physical properties of the mineral gypsum.

During late 1772 Lavoisier turned his attention to the phenomenon of combustion, the topic on which he was to make his most significant contribution to science. As he experimented with combustion, he noticed that when phosphorus (phosphates since phosphorus does not appear in its elemental form) burned it combined with the air to form phosphoric acid. He noticed a similar phenomenon with sulfur.

As he continued his experiments in chemical reactions he carefully weighed the reactants and products of a said reaction a in a sealed glass vessel so that no gases could escape, and concluded that nothing was gained or lost just chemically changed. THis would be repeated by many other chemists.

He is credited with discovering or isolating several chemical elements including nitrogen,

hydrogen,

sulfur,

phosphorus,

and most importantly, oxygen.

Unfortunately, he got caught up in the French Revolution and was guillotined in 1794 at age 50. Thanks for checking out this science history post and tune in tomorrow to learn more about March Madness semifinalist Lisowicia! Fossilize you later!

I have learned something amazing which is that the Chinese word for sodium (Na) is … 钠 (nà)! If only they all matched like that!!

Ex: 低钠酱油 (dī nà jiàng yóu) - low sodium soy sauce

Sometimes you may see the word 卤 (鹵/滷，lǔ, halogen or salt) used to describe dishes or sauces, such as 卤肉饭 (lǔ ròu fàn, braised pork rice), 打卤面 (dǎ lǔ miàn, noodles with thick gravy), 卤虾油 (lǔ xiā yóu, shrimp sauce).

Here is the first three rows of the periodic table!

Hydrogen (H) - 氢 (qīng)

Helium (He) - 氦 (hài)

Lithium (Li) - 锂 (lǐ)

Beryllium (Be) - 铍 (pí)

Boron (B) - 硼 (péng)

Carbon (C) - 碳 (tàn)

Nitrogen (N) - 氮 (dàn)

Oxygen (O) - 氧 (yǎng)

Fluorine (F) - 氟 (fú)

Neon (Ne) - 氖 (nǎi)

Sodium (Na) - 钠 (nà)

Magnesium (Mg) - 镁 (měi)

Aluminum (Al) - 铝 (lǚ)

Silicon (Si) - 硅 (guī)

Phosphorus (P) - 磷 (lín)

Sulfur (S) - 硫 (líu)

Chlorine (Cl) - 氯 (lǜ)

Argon (Ar) - 氩 (yà)

And a few more useful ones:

Iron (Fe) - 铁 (tiě)

Gold (Au) - 金 (jīn)

Silver (Ag) - 银 (yín)

Examples:

地铁 (dì tiě) - subway; short for (地下铁道, “underground iron path”)

金银 (jīn yín) - gold and silver, can be used to refer to ancient currency

穿金戴银 (chuān jīn dài yín) - to be dressed in gold (clothes) and silver (ornamentation) (idiom)
