Which conclusion could be made from Ernest Rutherford’s gold foil experiment?

Chemistry
2 answers:
boyakko [2]3 years ago
5 0

The conclusion was that there must be space between the particles of an atom. The way he knew this is because while some of the radiation reflected off of the gold foil, other radiation went right through it.

Answer:

Mass of an atom is concentrated in a positively charged core called the nucleus.

Explanation:

Rutherford gold foil experiment expanded our understanding of the structure of an atom. When positively charged alpha particles were bombarded against a thin gold foil, Rutherford observed that majority of particles passed through the foil undisturbed whereas a small percentage retraced their path.

There were two main conclusions from the experiment:

-Since most alpha particles simply passed through undeviated this suggested that majority of the space inside the atom is empty

- Also, since some of them completely bounced back this suggested that there is a positively charged core in which the mass of the nucleus is concentrated.

Masteriza [31]

Answer:

B. electrons and protons.

Explanation:

In an electrically neutral atom of any element, there are equal number of protons and electrons in the atom.

Protons are the positively charged particles in an atom.

Electrons are the negatively charged particles within the atom.

  When the number of protons and electrons are the same or equal, the atom is neutral.

But when there is an imbalance, an ion results.

The concentration of urea in a solution prepared by dissolving 16 g of urea in 20 g of H2OH2O is ________% by mass. The molar ma
Arada [10]

Answer:

44

Explanation:

Given that :

Mass of solute = Mass of urea = 16g

Mass of water = 20g

Mass of solution = (mass of solute + mass of solvent) = (mass of urea + mass of water) = (16g + 20g) = 36g

Percentage Mass = (mass of solute / mass of solution) * 100%

Percentage Mass = (16 / 36) * 100%

Percentage Mass = 0.4444444 x 100%

Percentage Mass = 44.44%

Percentage Mass = 44%
