Describe the Rutherford model

Physics
1 answer:
AlexFokin [52]3 years ago
4 0

Answer:

The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect.

Atomic theory year: 1911

A student uses a spring to launch a marble vertically in the air. The mass of the marble is
Fed [463]

Answer:

the maximum height reached by the marble is 11.84 m.

Explanation:

Given;

mass of the marble, m = 0.02 kg

extension of the string, x = 0.08 m

force applied to the string, F = 58 N

Apply the principle of conservation of energy;

elastic potential energy = gravitational potential energy

¹/₂fx = mgh

h = \frac{Fx}{2mg} \\\\h = \frac{58 \ \times \ 0.08}{2 \ \times \ 0.02 \ \times \ 9.8} \\\\h = 11.84 \ m

Therefore, the maximum height reached by the marble is 11.84 m.

What are the chemical properties of elements related to?
MAVERICK [17]
<span>The chemical properties of ANY atom are found in how they react with other elements.

A. An element's symbol - Nothing to do with reactions

B. The average atomic mass -The mass doesn't react

C. The number of electrons that occupy the outer shell - the only part of the electrons that move, SO they are involved in the reactions (answer)

D. The total number of electrons - The inner electrons cannot move from the atom unless there is ALOT of energy given to them, so these cannot react and would not contribute to the chemical properties.</span>
