How do polonium and radium affect your life today?
Polonium and radium's affect on our lives today are for example the meters on our cars, they glow because of the radium and also some wristwatches the light you get when you press the button on the side. Radium was discovered by a woman named Marie Cuire, she's married, but she obviously died because of too much radium.
Where was the scientist who invented Radium from?
Radium was discovered by Marie Curie, Pierre Curie and Gustave Bemont in 1898.
What year did Madame Curie discover elements of radium and polonium?
Polonium and was discovered in 1898 by Pierre Curie and Marie Curie.
It was first discovered in 1898.
The announcement was made on December 26, 1898 by Marie Curie, Pierre Curie, and Gustave Bémont in Paris, France.
For works including this discovery, Marie Curie was awarded the Nobel Prize for Chemistry in 1911.
Radium was discovered in 1898 by Marie Curie, Pierre Curie and Gustave Bemont.
Who was the woman who discovered Radium?
Marie Curie also discovered polonium. Her husband Pierre helped in the investigation also. She started off by studying a variety of chemical compounds that contained uranium. She discovered that the strength of the rays that came out depended only on the amount of uranium in the compound. It had nothing to do with whether the material was solid or powdered, dry or wet, pure or combined with other chemical elements. If you had a certain amount of uranium a certain number of uranium atoms-then you got a certain intensity of radiation. Nothing else made a difference.
The Nobel Prize in Physics 1903 was divided, one half awarded to Antoine Henri Becquerel "in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity",the other half jointly to Pierre Curie and Marie Curie.
Why is radium more important than gold?
The short version is that, just as certain numbers of electrons give inert elements and certain other numbers give highly reactive elements, the stability of a nucleus is dependent on the number of neutrons and protons. Some isotopes of gold contain the proper numbers of nucleons to be stable; no isotopes of radium do, so radium is radioactive.
What is the value of radium today?
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 rarely in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.

What are some characteristics of radium?
Radium is a radioactive element that emits alpha, beta, and gamma rays. It is silvery-white in color and is highly radioactive due to its unstable atomic structure. Radium is chemically reactive, with properties similar to calcium.
The first use of radium was in the preparation of luminescent paints for the instrument dials.
What is the first decay product of radium?
Radium decays in any of (at least) four different ways, depending on isotope and, in some cases, on luck, as some isotopes can decay in different ways.
The most important way radium can decay is by alpha emission. Nearly all naturally occurring radium decays this way, and so do the majority of synthetic isotopes. In this case, radium emits an alpha particle, which can be regarded as a helium nucleus, and the daughter atom is radon. The isotope of radon is depends on the isotope of radium involved; the mass number of the radon is always equal to the mass number of the radium minus four.
Some heavier radium isotopes undergo negative beta decay, in which case the decay products are an actinium atom and a negative beta particle, which can be viewed as an electron.
Some lighter radium isotopes undergo positive beta decay, in which case the decay products are a francium atom, a positive beta particle, which can be viewed as a positron, and an electron type antineutrino.
A few radium isotopes also rarely undergo what is called cluster decay, and the most important naturally occurring isotope, radium-226 is among these. Cluster decay involves emission of a nucleus larger than an alpha particle, and in the case of radium all known cluster decays emit carbon-14 nuclei. In this case, the daughter atom is lead, with a mass number that is 14 lower than the mass number of the parent. So radium-226 can emit a carbon-14 nucleus, leaving a lead-212 atom.
Why isn't radium used now a days?
Generally , Yes .
- Uranium-235 ( a radioactive isotope ) is used in nuclear power stations to provide energy .
- As thickness gauges ( alpha particles are used to control the thickness of paper , and beta particles to control that of aluminum ) .
- As tracers ( This method is used in medicine to detect brain tumours and internal bleeding , in agriculture to study the uptake of fertilizers by plants , and in industry to measure fluid flow and checking for leaks , in pipes ) .
- Radiotherapy ( Gamma rays from strong cobalt radioisotopes are used in the treatment of cancer ) .
- Sterilization ( Gamma rays are used to kill bacteria in medical instruments ) .
- Preservation of food ( Again Gamma rays kills bacteria in food , safely ) .
- Archeology ( in determining the age of rocks and historical foundations ) .
Is uranium the same thing as radium?
No, nuclear energy is due to a phenomenon called the "binding energy" of the atom which every element has and is a result of the strong nuclear force. However releasing this "binding energy" to get heat and thereby do work is not possible in every element.
There are two practical ways to release this energy: fission of large massive atoms (e.g. uranium, plutonium) and fusion of small light atoms (e.g. hydrogen). Both fission and fusion have been used in nuclear weapons, only fission has been used in nuclear power plants. The stars use only fusion.
While most nuclear power plants operating today use only uranium as fuel, France reprocesses spent fuel and uses both uranium and plutonium as fuel. A few experimental nuclear power plant reactors (e.g. the Integral Fast Breeder) have been worked on that are actually capable of using all the transuranic elements as well as uranium as fuel, so that they generate no long lived waste products.
How many core electrons are in radium?
The atomic number of radium is 88 distributed such that:
- First energy level 2
- Second energy level 8
- Third energy level 18
- Fourth energy level 32
- Fifth energy level 18
- Sixth energy level 8
- seventh energy level 2
Accordingly, radium loses two electrons on ionization to be a positive ion.
How many protons neutrons and electrons are in radium 222?
Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
Is radium dangerous or explosive?
Yes. Radium is a highly radioactive alkali earth metal, and inhalation, injection, ingestion or body exposure to radium can cause chemical burns, radiation burns and can lead to cancer and other disorders. Radium is chemically similar to calcium, and it has the ability to replace calcuim in bones, which is extremely harmful. A link is provided to the Wikipedia article on radium.
After undergoing alpha decay an atorm of radium-226 becomes?
There are three types of radioactive decay, alpha, beta and gamma. Alpha decay is when an unstable, or radioactive, nucleus gives off an alpha particle, which consists of two protons and two neutrons. Beta decay is when a nucleus gives of a positron or an electron, called a beta particle, and gamma decay is when a nucleus gives off a gamma ray. A gamma ray is a highly energetic photon of light.

How many electron shells does radium have?
Rubidium has 5 electron shells.
The electron configuration of rubidium is [Kr]5s1.
Does radium react with other elements?
calcium will bond with the other elements in the alkaline earth metal family. that would include magnesium, barium. radium, strontium, and beryllium. it may also bond with other elements like chlorine and sodium, but I'm not sure on that one.
Um good try but im a science teacher with many colledge graduate degrees and actually nothing bons with Calcium
>>I'm rather sure that a science teacher could spell "college" and "bonds" correctly, especially if they have multiple college degrees. Since calcium is an alkaline earth metal, it is very reactive and will bond with just about anything. Some of these things are halogens (the 17th column of the periodic table) and most of the nonmetals. You won't find calcium in its pure form in nature; it's always bonded with something else.
When did Marie and Pierre Curie discovered polonium and radium?
Polonium was discovered by Marie Curie and Pierre Curie in 1898.
Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898.
Radium is a decay product of uranium and is therefore found in all uranium-bearing ores. (One metric ton of pitchblende yields 0.0001 grams of radium). Radium was originally acquired from pitchblende ore from Joachimsthal, Bohemia, in the Czech Republic. Carnotite sands in Colorado provide some of the element, but richer ores are found in the Democratic Republic of the Congo and the Great Lakes area of Canada, and can also be extracted from uranium processing waste. Large radium-containing uranium deposits are located in Canada (Ontario), the United States (New Mexico, Utah, and Virginia), Australia, and in other places.
