has mass exactly equal to Au, where A is mass number of
element.
(a) A = 1
(b) A = 12
(c) A = 16
(d) A can take up any integral value from 1 to 110

Answer 1

Actinium 231, ²³¹ AC₈₉, emit in succession two β particles,

four α-particles, one β and one α plus several γ rays. What

is the resultant isotope?

(a) ²²¹ Au₇₉ (b) ²¹¹ Au ₇₉

(c) ²²¹ Pb ₈₂ (d) ²¹¹ Pb ₈₂If u denotes 1 atomic mass unit. One atom of an element
