9 The relative abundances of the two isotopes of chlorine are shown in this table: Relative abundance
Isotope
35C1
75%
3701
25%
Use this information to deduce the mass spectrum of chlorine gas

35.50 atomic mass

Explanation:

1. Multiplicate each isotope mass by its abundance

35 uma x 75% = 26.25 amu

37.01 uma x 25% = 9.2525 amu

2.  Add the values

26.25 +  9.2525  = 35.50 atomic mass

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
