Rutherford used alpha particles in his gold foil experiment. How might the results of his experiment have changed if he
had used negative particles instead of positive particles?

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
