Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.
Possible use in radiotherapy of some cancers.
Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.
Radium was not changed ! It is impossible.
radiun changed the world by of cancer treatments and curing skin damage.
Radium was discovered in Paris, in1898, by Marie Curie, Pierre Curie and Gustave Bemont.
All chemical elements after uranium and promethium, technetium.
Since Radium is in the alkaline earth metal group, and we know that as you move down the group, it gets more reactive. So, since Radium is the last element of the group, another property of Radium is that it is highly reactive in nature.
There was no first discovered planet. Mercury, Venus, Mars, Jupiter, and Saturn have been known since ancient times from before anything was actually documented. They have no particular discoverer.
No, Iron was known to man since ancient times... but magnesium was discovered in 1808 by Sir Humphrey Davy.
Crude oil has been known of since before pre-recorded history. No one can say who first discovered it.
radium was founded by Marie curie and Pierre curie.it was termed rad which means first in polonium since it was the first radioactive substance to be discovered
All chemical elements after uranium and promethium, technetium.
The bifocals have changed alot since they were first invented. They have changed into different sizes, shapes and forms. They had also changed into sunglasses.:)
When it was first discovered it was only used for specific things. Now, it's a become a very important part of our lives and is used in the smallest things. E.g. phones, T.V., etc
Nothing's changed
no they have not
The first metals to be discovered was gold. It has been used since 6000 B.C

Many more elements have been discovered and the discovery that mercury is poisonous.
No, it hasn't changed since it was first made.
No one discovered "blindness" It has been with us since the first group of Humans walked the earth.
