Make the correct choices in the following:
(a) In one atom of copper (mass number 63, atomic number 29) there are
What is a.m.u?
An imaginary radioactive element `"_92X^235` decays to form X1; X2; X3; X4; X5 and X6 nuclides, by ejecting two β-particles, followed by α-particles and again two β-particles, followed by α-particle. Represent the various nuclear changes in the form of an equation. State the mass number and atomic number of X6. List the isotopes and isobars in the above nuclear equation.
What changes will take place in the mass number and atomic number of the nucleus Y if it emits gamma radiations?
The nucleus of an atom does not contain electrons. Explain how is it possible for the nucleus to emit a beta particle which is fast moving electron.
Explain briefly what changes take place within the nuclei when beta particles are emitted by a radioactive substance.
What are beta rays and gamma rays?
An element 92U238 losses one alpha particle, and then one β-particle and then again one β- particle to get the final nucleus bQa.
(i) Write down the values of a and b.
(ii) State the relationship between the nuclei P and Q.
An isotope of uranium is 92Y238, i.e., it has mass number 235 and atomic number 92.
Do all isotopes have the same number of neutrons?
