Radioactive elements comprise a majority?
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
Why radioactive decay is always first order reaction?
This is because only one isotope decay.
Why 7Th period elements are radioactive?
The 7th period elements are radioactive because they have large atomic numbers with unstable nuclei. The high number of protons and neutrons in the nucleus leads to an imbalance in forces, making the atoms prone to radioactive decay in order to achieve a more stable configuration. Additionally, the presence of unpaired neutrons or protons in these heavy elements contributes to their radioactive nature.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy?
The critical mass.
Atoms of two or more different elements combined?
They combine in order to involve in chemical bonding.
What is meant by the order of a chemical reaction?
The reaction order is the law in which determines which elements will begin the process first. It is dependent upon the Kinetic energy of each element. The reaction order in chemistry is difficult to determine.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy called?
The critical mass.
Radioactive elements include all those elements whose nuclei contain what?
Radioactive elements include all elements whose nuclei either:contain protons more than 83 proton, orcontain neutron to proton ratio out of the stability ratio.refer to related question below.
Why photochemical reaction is zero order reaction?
Photochemical reactions often involve the absorption of photons to initiate the reaction, rather than the concentration of reactants. This means that the rate of the reaction is not dependent on the concentration of reactants, leading to a zero order relationship between reactant concentration and reaction rate.
In what order are redox reaction balance?
To complete the balanced redox reaction, you simplify the equation by removing common elements on both sides.
Is it true that radioactive decay results in the fusion of stable nuclei along with the emission of multiple types of radiation?
No. Fusion is the combining of light elements into heavier elements (like 2 deuterium into 1 helium). radioactive decay is when you have an unstable atom releasing energy (and sometimes matter) in order to reach a more stable state.
Why is uranium radioactive?
Positives repel each other. In an atom, the nucleas is full repelling protons with their positive charge. It is the nuclear force that holds them together in the nucleus. A Helium atom has only 2 protons which makes it more stable.Uranium on the other hand, has 92 protons all squashed together. This makes it very unstable which allows it to undergo gamma radiation.That is why Uranium is radioactive.Unstable atoms as uranium are radioactive; the stability depends on the ratio between protons and neutrons.
