The graph provided shows the accumulation of nonradioactive atoms during the decay of a radioactive substance. Why does the correct graph approach the horizontal line at y = 100? Check all that apply. The total number of atoms is 100.

The number of half-life cycles it takes for all the nuclei to decay is 100.

The final number of nuclei that can decay is 100.

i think slash and

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

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.
