Q6 of 40 Page 4

What is the charge and mass of a β-particle? From which part of the atom are β-particles emitted?

β - particles are nothing but highly energetic electrons. These rays are emitted straight from the nucleus.
These β - rays are formed, during radioactivity by breaking of neutron into a proton and an electron. The proton is retained in the nucleus while electron is rejected in the form of β - rays.

4 a) Who discovered the nuclear model of the atom?
b) Explain how Rutherford's atomic structure cannot explain the stability of atom? 5 Explain how Bohr's atomic model explains the emission and absorption of radiation. 7 a) The two elements, A and B have 17 electrons each in their atom. Element A has 35 nucleons while element B has 33 nucleons (nucleons are the total number of protons and neutrons in the nucleus). What is the relationship between these two elements? Explain.
b) The element A reacts with hydrogen in diffused light. Does the element B also react with hydrogen? 8 One isotope of carbon with atomic mass 12, occupies group 14 in the 2nd period in the long form periodic Table. Predict the position of another radioactive isotope of carbon with atomic mass 14?
