The Periodic Table
Transcript of The Periodic Table
Today (2013) there are 118 known elements.
There are 18 groups of elements. What are Elements? An element is any of the fundamental substances that consist of atoms of only one kind.
Elements are all around us and inside us!
Elements can react, the violent way, or the calm way. What are Atoms? Atoms are the smallest particles of an element that can exist either alone or in combination.
Atoms have protons, neutrons, and electrons.
Atoms are so small, they cannot be seen by the human eye. This is a diagram of an atom. Meet the Creator! While teaching, Dmitri Mendeleev created the Periodic Table in 1869. Dmitri Ivanovich Mendeleev
1834--1907 O 15.9994 Oxygen 8 Atomic number Element symbol Element name Atomic mass Hg Mercury isn't wet to touch! 80 Mercury 200.59 Fe 26 Iron 55.845 Elements Everywhere! Some of the elements in the air are nitrogen, argon, and oxygen.
Some elements in the ground are iron, carbon, sodium, and potassium.
There are even elements in outer space! Elements in You! Elements in your body help you live. They can be in your blood, your sweat, and in your organs. And Now...... Presenting a gallery of the elements! Iron is used to make steel. It is also the second-most abundant element on the planet. 15 P Phosphorus 30.973762 Phosphorus was the first element ever to be discovered. 18 39.948 Argon 52 Argon is used as filling for fluorescent lamps, electric light bulbs, incandescent lamps and for vacuum tubes. 127.60 Tellurium Te Tellurium is found in gold; a shiny, rare, and valuable element. Now it's Time to BLOW!!!! Chemical Reactions A chemical reaction is a process in which two or more substances are changed into other substances. Fireworks! Many different kinds of elements make fireworks dazzling and explosive.
Some elements are used as fuel for fireworks.
Some elements make the colors in a firework.
Some elements create the "BOOM" in a firework.
Some elements create special effects in fireworks. Rusting and Color-changing When iron (Fe) in metals combine with oxygen (O2) in the atmosphere, the metal begins to rust. The Statue of Liberty was originally brownish-orange. After a chemical reaction the Statue of Liberty is green today. Today Before Bombs!! All sorts of elements are used in bombs, that's why bombs make maximum destruction!
Most bombs contain elements that react the strongest.
Don't fool around with reactive elements. Nukes Nuclear weapons (nukes) are very, very, very deadly and destructive.
Nuclear weapons contain radioactive elements that are extremely reactive.
Within a second after a nuclear weapon explodes, everything within miles of the explosion will be destroyed. Thanks for Watching! Be safe, smart, and scientific with the Periodic Table of the Elements! By Daniel
