What is the top number in an isotope?

An isotope is identified by atomic number (element number or name), by mass number, and by atomic weight. The mass numberfor an isotope is listed as a leading superscript such as 29Si, which in this example is silicon containing 14 protons and 15 neutrons (a rarer but stable isotope of the element). Similarly the atomic weight is indicated by a superscript such as U235 , an isotope of uranium having 92 protons and 143 neutrons.The actual atomic weight is often expressed as a decimal number corresponding to the mass of the atom in "atomic units", where a proton is about 1.0072, a neutron 1.0086, and an electron about .00055 atomic units.


What is the Relative atomic mass of chromium?

Chromium is a meta element. Atomic mass of it is 52.


How much neutrons have uranium?

Uranium has many isotopes and each isotope has a different number of neutrons (N). N = atomic weight of the isotope - atomic number of uranium (A=92) The number of neutrons of the isotope 92U238 is 238-92=146 and the number of neutrons of the isotope 92U235 is 235-92=143.


What atomic number would an istope of U have?

Uranium is a non metal element. Atomic number of it is 92.


How can you use the nuclide symbol to determine how many neutrons a particular isotope has?

The number of neutrons is the difference between the mass number and atomic number. For example U-235 means mass number equals 235. If we know that thge uranium atomic number is 92, then the number of neutrons for U-235 is 235-92 = 143 neutrons.

How many electrons are in isotope U-238?

Isotope U-238 has 92 electrons. This number corresponds to the atomic number of uranium, which is 92.


What is the symbol for the nucleus of each isotope of uranium?

The symbol for the nucleus of each isotope of uranium is U. Each isotope will have a different number of protons and neutrons, but they will all have the element symbol U as their nucleus.


What does the 235 mean in U-235?

The "235" in U-235 refers to the atomic mass number of the isotope of uranium. This number indicates that the nucleus of this isotope contains 92 protons and 143 neutrons, resulting in a total atomic mass of approximately 235 atomic mass units. U-235 is significant in nuclear reactions, particularly in nuclear fission, as it can sustain a chain reaction.


How much protons neutrons and electrons are in roentgenium?

Roentgenium (Rg) has 111 protons and an atomic mass of approximately 282 u. Since atomic mass - atomic number = number of neutrons, Roentgenium is estimated to have around 171 neutrons. In a neutral atom of Roentgenium, the number of electrons would also be 111.

The iodine isotope with 74 neutrons?

An isotope of iodine with 74 neutrons would have a mass number of 53 +74 = 127. Therefore its symbol would be I -127 or 127 C 53. 127 and 53 should be written as superscript and subscript respectively before writing the chemical symbol of iodine when using the later (127 C 53).Ê 53 is the atomic number of iodine.ÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊ
