Was radium used in the nuclear bomb?

If you are asking about the only two nuclear bombs used against a nation in world war two, I will answer it. The nuclear bomb used in Hiroshima was an uranium bomb. The second one used in Nagasaki was a plutonium bomb.

Radium could have been used in the neutron source, but is far too expensive and gives off too much Beta & Gamma radiation which could have damaged the bomb. Polonium was used in the neutron source instead.

What is the meaning of the song 'Radium Eyes' by Count Zero?

Radium Eyes by Count Zero MeaningIts a love song about two lovers separated by war (its set during the Philippene War) and hes talking about her eyes either being the color of Radium (the element) in its pure form (when it hasn't been exposed to air) , which is almost pure white , or when its been exposed to air, in which it turns black

Can you give a brief account of radium?

It was discovered by Marie and Pierre Curie in 1898 from a sample of pitchblende (uranium ore). Marie won the Nobel Prize in chemistry in 1911 for this discovery. All isotopes of Radium, of which four occur naturally, are radioactive. It's an alkaline earth metal (like calcium, magnesium, etc.) and acts very similar to barium.

Radium is found in nature in uranium ores since various radium isotopes are part of various uranium decay chains. It mostly decays into radon.

It's best nuclear physics use, since that's the category this "question" was dumped in, is as a neutron source when mixed with beryllium.

How did Marie Curie discover polonium and radium?

Marie Curie was interested in the recent discoveries of radiation. Wilhelm Conrad Roentgen had discovered X rays in 1895, and in 1896 Antoine Henri Becquerel had discovered that the element uranium gives off similar invisible radiations. Curie thus began studying uranium radiations, and, using piezoelectric techniques devised by her husband, carefully measured the radiations in pitchblende, an ore containing uranium. When she found that the radiations from the ore were more intense than those from uranium itself, she realized that unknown elements, even more radioactive than uranium, must be present. Marie Curie was the first to use the term radioactive to describe elements that give off radiations as their nuclei break down.Pierre Curie ended his own work on magnetism to join his wife's research, and in 1898 the Curies announced their discovery of two new elements: radium and polonium (named by Marie in honor of Poland)

What is the origin of so long used to express goodbye?

"So Long - farewell, Northern expression imported into Britain by soldiers serving in Malayan-speaking countries. Malayan salutation, Salang, a corruption of Arabic Salaam=peace."

It is of course an expression used in all English - speaking countries, not just the north of England, but maybe it first appeared there. However there are other opinions as to origin of the phrase.

It is also conceivable that the expression stems from the Irish (Gailge) word "slán," in which the accent lengthens the 'a' so that the word is pronounced 'slawn,' which sounds very similar to 'so long.' The word which is a shorted version of the expression "slán go fóil," which literally means 'goodbye for now.'Due to the widespread use of the expression 'so long' in the United States the theory is that it was introduced by Irish immigrants in the mid-nineteenth century and then spread memetically.

How do you calculate protons neutrons isotopes for radium?

Because the atomic number of radium is 88, radium has 88 protons.

The number of neutrons is different for each isotope:

Number of neutrons = Atomic mass of an isotope - 88

For example radium 226 has 138 neutrons.

Which scientist discovered the element radium?

Radium was first discovered in 1898 by Marie Skłodowska-Curie and her husband Pierre Curie, and Gustave Bémont, living and researching in Paris, France.

Radium was discovered in pitchblende coming from North Bohemia, in the Czech Republic.

What is radium used for?

Self-luminous paints (only in the past, before 1930), Ra-Be neutron sources, preparation of radon from RaCl2 solutions, medical uses for the treatment of conditions such as cancer (now being replaced by radioactive cobalt, 60Co sources, 137Cs, etc.).

Its use in medicine has declined because of its cost, and its use in consumer goods (to illuminate watch and clock hands and numbers, as well as instrument dials) was halted because it can cause radiation injury. It is still used for some radiography and as a source of neutrons.
