1.charge of nucleus =positive.
Charge of atom=neutral
2.Rutherford's conclusions from the alpha particles scattering experiment were:-
•The positive charge occupies very little space inside an atom.
•the nucleus is much smaller than the size of an atom.
3.No, according to me there are no drawbacks but during this experiment neutrons were not yet discovered.

Sir I understood everything that you have shown in the videos

[AjayAjay-djdr]

Sir your way of teaching was quickly understandable

[ajoymondal]

You are the best teachers of first ten teachers.Excellent!

1. Nucleus is positively charged.
Protons and neutrons are present in a nucleus, as protons are positively charged and neutrons have no charge, it is positive.
Atom is electrically neutral. Because, protons and electrons are equal in magnitude but opposite in charge so they neutralize each other.

2. Most of the space inside an atom is empty.
The positive charge of the atom occupies very little space.
The positive charge and mass of an atom is concentrated in a small space within the atom.

3. Yes
Rutherford said that the electrons revolve around orbits. If they do then they are in uniform circular motion. Anything in this motion, moves with acceleration. If it accelerates then it must radiate energy. If electrons radiate energy then it would be drained of all its charge and finally fall into the nucleus of the atom.
This would mean that atom is unstable. And if it was then matter would not have existed in the way we know it does. But we know that matter is stable. So, Rutherford couldn't explain the answer to this.


Hope this helped.

1. The nucleus is positively charged and an atom is electrically neutral because protons and electrons has equal magnitude but opposite charges, so when they come in contact they neutralise each other.



2. Electrons revolve around the nucleus in circular paths.
The size of the nucleus is small compared to the size of the atom.
There is a positively charged centre known as the nucleus.


3. Yes
According to Rutherford's model electrons move in circular or spiral paths .Which means that they posses circular motion. And anything that possess circular motion moves with acceleration. if it accelerates that means it radiates energy. If electron radiates energy it would eventually get drained of all it's charges and then crush into the nucleus of the atom.
This would mean that atom is not stable and that Rutherford model does not approve the stability of atom. And if atom is unstable then matter which we know is stable won't have existed in the way we know it does. So, Rutherford couldn't explain this.


And also Sir you didn't talk about bohr's model of atom

U r best teacher in th world



U r explain is god level 😍😍😘😘😘😘😘😘😘😘😘😘

[eshwarigp]

Sir,
My teacher ..only suggested ur channel...Sir Your teaching was amazing ...I can understand easily.... thanks for all your effort

[lunjapaobaite]

Q1. Chare of a nucleus is +ve because, nucleus contain neutron(neutral) and proton(+ve).
Q2.He conclude that in an atom there is nucleus and electron revolve around the nucleus.
Q3. Yes, there are draw back of Rutherford's model of atom

[tulasilakshmi]

You are making learning easy for students thank you sir

[saisai-pvql]

Sir ur r perfect teacher for physics l really like your videos

[divyabajpai]

I wished that you are my tution teacher
doubt i would crack Jee mains the next day.

[GlobalElevatorAcademy]

Thank you. It’s difficult to find high-quality information. I honestly appreciate individuals like you!
Take care!!

[the.idealsahil]

2:38 Let's appreciate him as he at the watermelon seeds for us😅

[slife]

nice, I understood everything you are very good teacher

[pankajpateriya]

Excellent work. Because of practical use of instruments, and speech rate slow, clear that is good 👍👍👍👍👍👍👌👌👌👌👌👍👍 please creat more vedio on science

[power.factor]

This is how a teacher should be. Wonderful 😊

[EmmanuellaOmowaye-lstu]

1. A nucleus is positively charged while an atom is electrically neutral.
Rutherford discovered that the size of the nucleus is relatively small compared to the size of the atom. He also discovered that the nucleus of the atom is found at the center of the atom.
Rutherford's experiment could not explain why the negatively charged electrons when not disappearing into the positively charged nucleus.

[anupamnair]

Thank you sir . Your explanation is very clear .

[akshaynarang]

Sir love ur videos they are really good and u explain the entire thing very well
