Q8 of 40 Page 4

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?

The long form periodic table is based on the atomic number of the elements. Since the two isotopes of carbon possess the same atomic number 6, the position of radioactive carbon with atomic mass 14 is same as the other isotopes of carbon with the atomic mass 12.(i.e. 2nd Period Gr14).

6 What is the charge and mass of a β-particle? From which part of the atom are β-particles emitted? 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? 9 a) What is the name given to the rays, traveling from cathode to anode?
b) Do the cathode rays always consist of electrons only, whatever be the gas enclosed in the discourage tube? 10 Why are electrons in the outermost shell known as valence electrons?
