Many people ask why the symbols of the Many people ask why the symbols of the elements are so different from their names. elements are so different from their names. Their symbols come form their Latin word of Their symbols come form their Latin word of the element. For example, the element. For example, IronIron in Latin is in Latin is called “called “FeFerrum”, that’s why its symbol is rrum”, that’s why its symbol is FeFe..

How important is How important is Iron?Iron?

Iron is a very important element, Iron is a very important element, especially for our body. If we wouldn’t especially for our body. If we wouldn’t have iron in our body, we would die. have iron in our body, we would die. When we don’t have enough iron in our When we don’t have enough iron in our body (Iron Deficiency) is extremely body (Iron Deficiency) is extremely dangerous because it causes anemia. dangerous because it causes anemia.

It is also important because many It is also important because many things are made of iron, and it is things are made of iron, and it is unique. Iron is a very strong metal, so it unique. Iron is a very strong metal, so it is helpful. is helpful.

What are the causes of Iron What are the causes of Iron Deficiency? Deficiency?

The causes are divided into 2 main The causes are divided into 2 main categories:categories:

o People who don’t have a good diet: who doesn’t eat vegetables, meat, fruit (Vitamin C)..

o Taking antacids reduces the amount of iron in our stomach

o Younger kids need more iron Rapid growth

o Pregnancy, because iron is needed for 2 people not 1!

o People who donate blood they lose it because it is located into blood.

Not taking enough Iron into the body

Needs more iron than normal

Half LifeIsotope

Half-life: the time required for one half of the atoms of an amount of radioactive substance to disintegrate (break into very small pieces).

6060FeFe is an extinct is an extinct radionuclide which is which is 1500000 years.1500000 years. 5656FeFe it has the most stable nucleus, that’s it has the most stable nucleus, that’s why it’s impossible to performwhy it’s impossible to perform fusion with with it. it.

5757FeFe is the only stable isotope which has a is the only stable isotope which has a spin.5454FeFe is a non-radioactive stable isotope. is a non-radioactive stable isotope.

5858FeFe is a non-radioactive stable isotope. The is a non-radioactive stable isotope. The iron we have in our body is mostlyiron we have in our body is mostly 5858FeFe..

Radionuclide: an atom with an unstable nucleus.

Fusion: a nuclear process in which two light atoms, and a heavy atom, unite. It releases energy, which helps the sun and the stars.

Spin: a moment in which the atoms move in a circular way.

What products are made from What products are made from Iron?Iron?

With huge amounts of iron, you can With huge amounts of iron, you can make steel. Steel can be made from make steel. Steel can be made from different substances, but it’s mostly different substances, but it’s mostly Iron, and of course, if you add more Iron, and of course, if you add more iron, and less of something else you iron, and less of something else you will come up with an isotope of steel. will come up with an isotope of steel.

The red water is due to the iron in the rocks.
