10 Most Dangerous Chemical ElementsChromium (Cr) photo: Atoma. Mention chromium and most people are thinking shiny car parts. Hydrogen (H) Hydrogen. The smallest and most abundant of all the elements, Hydrogen might not seem like the most obvious choice. Lead (Pb) Lead. Beryllium (Be) Beryllium. Fluorine (F) Fluorine.


Carbon, nitrogen and hydrogen are flammable elements in the periodic table. Phosphorus is also very flammable. You find phosphorus on the head of a match.

The thirty or so heaviest elements are all radioactive to some degree. Generally, the heavier the more radioactive. Listing those wouldn’t make for a very interesting top 10 deadliest elements so I’ve skipped a bunch of these and gone for the most exciting dangerous chemical elements. 10. Chromium (Cr)


Although hydrogen is the most flammable element, the most flammable chemical probably is chlorine trifluoride, ClF 3.This is a colorless, toxic, corrosive gas or pale greenish-yellow liquid that is so reactive that it initiates combustion of just about any material you can name, and it doesn't even require an ignition source to get the fire started!


Periodic table of Flammable Metals illustrates the significance of the position of Flammable Metals in the modern periodic table. Since its inception, the periodic table has evolved time and again, due to the discoveries of certain new metals and their properties.


The table is arranged by how each element react with other elements. Periodic means the pattern repeated. It wasn't until later that we figured out why. The right most ones, called the nobel gases, are not reactive.


None. There are no explosive elements. Typical explosives are compounds, which function by exothermic decomposition reactions. (They rapidly break down into simpler substances, usually gases, with a release of heat energy.) Some elements can form ...

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
