<h3>What is Half life period ?</h3>

A half life is a measurement of the slope of an exponential decay function.

It is also defined as, the time it takes to halve the concentration of something in a process.

Each half life you will have half of what you had at the beginning of a given half life.

Mekhanik [1.2K]

The copper atom is oxidized while the silver is reduced.

<h3>What is a redox reaction?</h3>

A redox reaction is one that occurs between an oxidizing agent and a reducing agent. One specie is oxidized while the other specie is reduced in the reaction.

In this case, the oxidizing agent is the silver and the reducing agent is the copper atom. The copper atom is oxidized while the silver is reduced.

The complete equation is;

Cu(s) + 2AgNO3(aq) -----> Cu(NO3)2(aq) + Ag(s)

Ionically;

Cu(s) + 2Ag^+ -----> Cu^2+(aq) + Ag(s)

the results of Rutherford’s gold foil experiment disproved the model of the atom that his mentor and colleague had proposed. How
nignag [31]
During the development of a scientific theory, numerous scientific experiments are carried out through different approaches. A theory holds true as long as no experiment disproves a theory. 
This experiment showed that when testing a theory with a new approach, it is possible that it may be disproven, meaning scientists should not settle for any explanation for a natural phenomenon that is not completely explained; instead, they should continue to investigate and hypothesize to improve their understanding of the phenomenon.
