How many neutrons does uranium 238 have? How many isotopes does californium have? What is the difference between atomic number and mass number of an atom? What is the atomic mass of an electron? An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom?
What is the symbol for the isotope with 80 protons and a mass number of 202? How many neutrons does it have?Mass Number:The mass number of an atom represents the number of nucleons in the nucleus of an atom. Nucleons is a general term for p...
Suppose you take a really heavy atom—a stable kind of uranium called uranium-235. Each of its atoms has a nucleus with 92 protons and 143 neutrons. Fire a neutron at uranium-235 and you turn it into uranium-236: an unstable version of the same atom (a radioactive isotope of uranium)...
How many protons, electrons, and neutrons are in the following isotopes. (a) Uranium-235 (b) Hydrogen-3 (c) Silicon-29 How many protons and neutrons does oxygen-18 have? What is its mass number? The 57Fe atom has how many neutrons? How many neutrons are in the nucleus of an atom ...
It's not that simple though. An atom's properties can change considerably based on how many of each particle it has. If you change the number of protons, you wind up with a different element altogether. If you alter the number of neutrons in an atom, you wind up with anisotope. ...
40 lb = 18.1436 kgthere are 18.14 kilograms in 40 poundsFirst take the weight in pounds and multiply by 453.59. The resulting number is the weight in grams. To convert grams to kilograms, simply divide by 1000. Or, an easier option is to take the weight
The last type of particle radiation is known as neutron radiation; something that is created when atoms are either fused together or fissioned apart. Unlike all other forms of radiation, neutrons can actually turn things radioactive! This is because when a neutron smacks an atom it may stick ...
To understand this, first imagine an elementas a family with isotopes as its members. Everyatomof a given element has the same number of protons, but different isotope cousins have varying numbers of neutrons. Radioactive isotopesare not stable. They release a steady st...
Uranium-238 is also fissionable, but "fast" neutrons at higher energies are required to split it. This is often the process used in nuclear weapons. Nuclear fission results in radioactive nuclear waste in the form of the daughter isotopes produced by the splitting of the uranium or plutonium...
For example, when radioactive elements like uranium, radium and polonium decay, they release radioactive alpha particles. These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even ...
