What experimental evidence led to the development of this atomic model from the one before it? A few of the positive particles aimed at a gold foil seemed to bounce back. The colors of light emitted from heated atoms had very specific energies. Equations were used to identify regions around the nucleus where electrons would likely be. Cathode rays were bent in the same way whenever a magnet was brought near them.

Answers

Answer 1

Answer:

Few positive particles aimed at a gold foil seemed to bounce back is the evidence that is responsible for the development of atomic model. Rutherford performed an experiment in which alpha particles are allowed to fire on the gold foil.

Some of the particles bounced back which tell us that there are heavy particles present in the center of an atom.

Most alpha particles pass through the atom which tell us that there is a lot of empty space in an atom.

There is also a slight deflection that occur due to similar charge that tells us the element which is present in the nucleus has positive charge.

Answer 2

Answer:

Final answer:

The Gold Foil Experiment conducted by Rutherford, Geiger, and Marsden led to the development of the Rutherford Atomic Model. The results of the experiment suggested that atoms contain a densely packed, positively charged nucleus in the center with electrons orbiting around it, and mostly, atoms are composed of empty space.

Explanation:

The key experimental evidence that led to the development of the Rutherford atomic model from the Thomson model was the Gold foil experiment. As described, physicist Ernest Rutherford, along with Geiger and Marsden, pointed a beam of alpha particles at a thin piece of gold foil. They observed that a small fraction of these alpha particles bounced back, suggesting they hit a densely packed, positively charged center in the atom. Most alpha particles passed through the gold foil indicating that atoms are mostly empty space. These observations couldn't be explained by the previous atomic model (Thomson Model) where it was assumed that positive and negative charges were uniformly distributed throughout the atom. Therefore, Rutherford proposed a new model, where the atom consists mostly of empty space, with a densely packed, positively charged nucleus in the center and negatively charged electrons orbiting around it.

Answers

Irregular galaxy

A galaxy that has an unidentified shape is best classified as an irregular galaxy.

An irregular galaxy is a galaxy that has an undefined regular shape. These galaxies are composed of large amounts of young stars, gas, and dust. Irregular galaxies are usually small, disorderly in appearance, and without a nuclear bulge or any trace of spiral arm shape. Examples of irregular galaxies are the small and large magellanic clouds.

Justify a physician has a patient, age 42 whose blood pressure averages 141/89 mm hg. Why might the physician recommend healthful life choices to the patient.

Answers

Answer:

Due to high blood pressure.

Explanation:

The physician recommend healthful life choices to the patient because the patient has high blood pressure. The normal range of blood pressure is 120/80 mm hg whereas the high blood pressure is considered to be 140/90mm Hg so we can say that the patient has high blood pressure which can be normalize by attaining healthful life style such as eating healthy food, regular exercise and avoiding stress.

In which of the following ways might the effects of a mutation in a skin cell be different from those of a mutation in a sperm cell?Sperm cell mutations are more likely to get corrected since meiosis has two phases, while skin cell mutations have only the single phase of mitosis in which to be corrected. A mutated sperm cell will always be destroyed during meiosis before it leaves the testes, while skin mutations remain within the skin. There is little chance that a sperm mutation will affect the testes, while skin mutations almost always develop into cancer. The mutation in the sperm cell could be passed on to offspring, while the skin cell mutation could only affect the individual.
