Why is uranium 235 called uranium 235?
Uranium-235 is named for its atomic mass, which is approximately 235 atomic mass units. The number "235" refers to the total number of protons and neutrons in the nucleus of the isotope. Uranium has several isotopes, but U-235 is significant because it is fissile, meaning it can sustain a nuclear chain reaction, making it crucial for both nuclear power and weapons. The designation helps differentiate it from other isotopes of uranium, such as uranium-238, which has a different atomic mass and properties.
Which is an example of a highly unstable isotope that is often used in fission reactions?
Uranium-235 (U-235) is an example of a highly unstable isotope that is used in fission reactions. It undergoes spontaneous fission, releasing a large amount of energy and additional neutrons, which can then go on to induce fission in other uranium atoms, leading to a chain reaction.
What is the significant figure for 235?
All three figures are significant in 235
How many significant figures do 235?
Three of them.
How do you figure how many significant figures are in 235?
To determine the number of significant figures in a number like 235, you need to consider that all non-zero digits are significant. Therefore, 2, 3, and 5 are all significant figures. Additionally, trailing zeros after a decimal point are also considered significant. In this case, since there is no decimal point present, the trailing zero in 235 is not considered significant. Hence, the number 235 has three significant figures.
4 is what percent of 235?
2.35 is 1% so 4 = 4/2.35 = 1.70% to two significant figures
What is the significant figure of 235?

Write how many significant figuers does this figure have 235?
Three - all nonzero numbers are significant.
Which two notations represent different isotopes of the same elements?
Example with the istope 235 of uranium: - 235 92U (recommended) or - U-235
What times equals 235?
To find what times equals 235, you can express it as a multiplication problem, such as ( 1 \times 235 ) or ( 5 \times 47 ). Essentially, any pair of factors that multiply together to yield 235 will suffice. For example, ( 235 = 5 \times 47 ) or ( 235 = 235 \times 1 ).
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.
Which is not an example of fossil fuel?
Uranium-235, which powers nuclear fission
