Pitbulllover101 rutherford's famous gold foil experiments shot heavy particles at a thin sheet of gold foil. what did he observe, and why did these observations eventually result in the addition of a nucleus to the atomic model? some of the heavy particles bounced off the foil, because there are positive particles spread throughout the atom. some of the heavy particles bounced off the foil, because there is a dense, positive area in the atom. the heavy particles all passed straight through the foil, because the atoms are mostly empty space. the heavy particles all bounced off the foil, because the subatomic particles have mass and volume.

Some of the heavy particles bounced off the foil, because there is a dense, positive area in the atom.

Explanation:

In Rutherford experiment following is the observations made by the Rutherford

1). Major part of the alpha particles will go out undeviated which shows that major portion of the atoms vacant or empty space

2). Few part of the alpha particle moves out with deviation in path which shows that electrons moves in different shells and when alpha particles pass through a given electron then it will show the deviation in path

3). very few alpha particles will get deviated by 180 degree and returns to original path which shows the presence of nucleus. So nucleus is made up of positive charge which is concentrated at very small space

so here correct answer would be

Some of the heavy particles bounced off the foil, because there is a dense, positive area in the atom.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get
