Learn more at -- Within the periodic table loom many potential hazardous elements. Some elements are dangerous due to their toxicity. Others are dangerous because of how they respond, react, or even explode in the outside environment. And perhaps the most threatening elements are those that silently emit energy. So, which substances on the periodic table are the most dangerous Shannon Odell investigates.

These three are deadliest because other we can easily get away from radioactive elements
Thallium- Exposure can cause severe health issues, including hair loss, nerve damage, and organ failure.
Lead-Accumulation in the body can lead to neurological and developmental problems, particularly in children, as well as cardiovascular and kidney damage.
Mercury- It can damage the nervous system, kidneys, and immune system, and exposure can lead to tremors, cognitive impairments, and other serious health problems.

I've always found Technetium and Promethium particularly fascinating. They're like the Missingnos of the chemical elements - atomic physics dictate that they should exist naturally, yet they've never been found, and trying to reproduce them has typically undesirable results. It's almost like a couple of elements were just deleted, if such a thing were possible, and what humans have managed to create are more or less their glitchy remains.

As a rhenium atom, no I don't have anything funny to say. btw, the periodic table is outdated, with the new elements named. And btw, in no place did I hear the halogens (probably because you won't likely find them in pure form, fluorine is so reactive that you touch it it reacts. You will find bromine in pure form (if you make it yourself) or iodine (which is a common medicine. Chlorine isn't that much of a threat)

3: 23 Alpha particles (Helium) are the least hazardous of all the particles emitted from radiation, it can’t get past skin, clothes, etc. Beta particles (electrons) can penetrate more by getting through the skin and gamma (em waves) can get through anything.
It is said that we are running out of Helium, maybe we can make more from alpha particles

The Periodic Table is definitely one of the most important inventions in modern science. They way it is set up, how easy it is to understand, and the information it displays readily is genius. It is also one of the only inventions that shows us what we are missing which means we can never stop searching for new elements.

Hello student of science here. I've been told that Francium is not as reactive as Cesium due to quantum effects pulling the valence electrons closer. I was also told Bismuth is stable with a half life equal to more than the age of the universe. I was hoping to see you research or source on this

I love how most toxic elements are toxic because they disrupt processes that already happen instead of releasing something dangerous that kills us. Like arsenic and thallium which disrupt potassium in the human body or lead that disrupts calcium. So interesting.

Just a note: please don’t represent atoms or ions as a cluster of particles because then they are easy to confuse with molecules. This is obviously unless you’re talking of protons, neutrons and electrons. Otherwise,
Great work!

Fact of the day! This periodic table is pretty outdated (not really. Elements Uut, Uup, Uus, and Uuo have now been known as Nihonium (Nh, Moscovium (Mc, Tenessine (Ts) and Oganesson (Og)

it is important to mention that alpha particles are easily blocked by a paper sheet while beta requires more protection and gama only by concrete and lead

I once watched a documentary on Yasser Arafat who was supposedly killed by Polonium poisoning. That how I came to know that chemical element. Po.

Marie Curie invented the theory of radioactivity, the treatment of radioactivity, and dying of radioactivity.

reply

elements you consider safe for human consumption can also be dangerous if their amount exceeds required portion or reduces to zero
reply

One thing to note is that humans are the ones who made such discoveries, and some of them became too deadly for human society.
