Which contribution added to Rutherford's discovery of a positive nucleus?

Chemistry
1 answer:
posledela3 years ago
7 0

Answer:

A: Electrons are scattered in an atom.

Explanation:

Ernest Rutherford performed the gold foil experiment which gave a deeper perspective into what an atom really is. In his experiment, he bombarded a thin gold foil with an alpha particle source.

From the behavior of the alpha particles that associated with the gold foil, a number of conclusions were drawn:

  1. He suggested that an atom has a small positively charged nucleus where the bulk of the atomic mass is concentrated.
  2. Surrounding the nucleus is a large space which contains the electrons.

Alchen [17]

Answer:2-methylpropane

Explanation:

The structure of 2-methylpropane is contrasted with that of propane in the image attached. It is easy to see that 2-methylpropane contains a tertiary carbon atom which forms a stable radical. This stable radical formed will eventually lead to the yield of a single product which is 2-chloro-2-methylpropane. A tertiary radical is the most stable radical and often leads to the formation of a single product.

What common characteristic is generally shared by the elements at the center of a period?
Gnom [1K]
I think the correct answer would be C. The common characteristic that is shareed by the elements found at the center of a period would be that they are the least reactive species. Having lower value of electronegativity, there is less ionization of the atoms which would also contribute to less reactivity.

Answer : first opinion and also last
Expiation : Note that these last two reactions, and 2H + 2H → 4He + γ, .Nuclear fusion is a reaction in which two nuclei are combined to form a larger nucleus. Nuclear fusion is a reaction in which two nuclei are combined, or fused, to form a larger nucleus. We know that all nuclei have less mass than the sum of the masses of the protons and neutrons that form them. The missing mass times c2 equals the binding energy of the nucleus—the greater the binding energy, the greater the missing mass.
