What To Do When You Get Your Period

You may be familiar with the chemical periodic table from school, merely at that place'southward more than meets the eye with this seemingly simple scientific chart. Larn more than about the periodic table, including how it was developed and which elements have some interesting history that yous may not know most.

It Has a Single Author With a Singular Inspiration

Yous may already know that one human, Dimitri Mendeleev, is responsible for creating the periodic table. Merely what you may not know is that he was inspired by a deck of cards to write out each element on a carve up bill of fare and conform them in groups aCC0rding to their atomic weight.

Mendeleev was so confident in his arrangement that he was able to create spaces on the table for elements that had not yet been discovered, including gallium. However, his pride also caused him to initially turn down elements, like helium and other noble gasses, that didn't fit in with his structure.

Information technology's Notwithstanding Growing

It may seem that nosotros've discovered all there is to know about the natural world at this indicate, only scientific breakthroughs happen all the time. New elements are notwithstanding being added in the 21st century.

That'south Bananas

Bananas are well known to contain a high concentration of potassium, which is both an essential nutrient and an element on the periodic table. This fact frequently gets blown out of proportion, bananas actually incorporate a mildly radioactive form of potassium. They're completely safe to eat, though, and yous should ignore whatsoever implications to the opposite.

Golden Hour

Gold is not only an element on the periodic table, it's too a color unto itself. The metal has its warm yellowish hue thank you to energy level shifts in gold electrons, which causes the metal to absorb the blue cease of the light spectrum.

Gallium: A Chemical science Demo Favorite

Gallium, one of the elements that Mendeleev predicted, is a favorite selection for chemistry classroom demonstrations. This solid metal liquefies at a relatively low temperature (around 85 degrees Fahrenheit), meaning yous can shape it into a spoon that will melt into liquid if you use it to stir a hot cup of tea.

Mercury Madness

Sir Isaac Newton is widely known as a genius, just he famously struggled with mental illness late in his life. Modern scholars believe this is probable due to mercury exposure during his experimentation with alchemy.

Over-the-Counter Mercury Poisoning?

Other historical figures had run-ins with mercury besides. Lewis and Clark are said to accept brought mercury-based laxatives with them on their due west journeying. The pills were charmingly named "Rush's Thunderbolts."

Leaded Gasoline and Crime Rates

Mercury isn't the only element on the periodic table linked to behavioral issues. Lead has also been shown to cause developmental issues that may atomic number 82 to erratic beliefs in adults. Many reputable sources believe that the switch from leaded to unleaded gasoline is causally related to a abrupt driblet in crime about 20 years later.

Temporary Names for New Elements

When new elements are discovered, they're subject to rigorous peer review before they're then verified past the International Union of Pure and Applied Chemical science. Elements are usually given temporary names at this indicate, and are given their permanent names aCC0rding to international guidelines.
