What was the main weakness of Bohr's model of the atom?

Chemistry
1 answer:
dexar [7]2 years ago
5 0

Answer:

A) the two weaknesses of bohr's atomic model are : 1) the path of electron around nucleus is considered to be circular of definite radius but in reality it can be at any distance from the nucleus. 2) the model is based on spectra of atoms and newton's laws of motion which are not applicable to microscopic particles.

Write the equation for the reaction described: A solid metal oxide, Ag2O, and hydrogen are the products of the reaction between
Harlamova29_29 [7]

Answer:

2Ag + H2O -----> Ag2O + 2H

Explanation:

2Ag + H2O -----> Ag2O + 2H is the equation of the reaction between metal and steam. Silver reacts with water (steam) forming silver oxide and hydrogen gas. When the metals react with steam it produces the solid metal oxide and hydrogen gas. On the surface o metals, a protective layer of aluminium oxide is formed that keeps water away from the metal so we can say that silver oxide and hydrogen are formed from the reaction of silver metal and steam.

How many moles of aluminum are equivalent to 4.816x10^24 atoms? 12.5 8 1.25 0.8
kotegsom [21]

Answer:

8

Explanation:

1 mole = 6.02 × 10²³ atoms

? moles = 4.816 × 10²⁴ atoms.

? Moles = 4.816 × 10²⁴ ÷ 6.02 × 10²³

? Moles = 8 moles

8 moles of aluminum = 4.816 × 10²⁴

Veronika [31]

Answer:

Explanation:

After the glorious appearance of Full Moon, the lunar shape starts to wane, meaning it gets smaller. It's visible later at night and into the early morning, and we see a steadily shrinking shape of the lunar surface that's being lit up.

Compare and contrast the Bohr model and the electron cloud models of the atom.
bogdanovich [222]

Here we have to compare the Bohr atomic model with electron cloud model.

In the Bohr's atomic model the electrons of an element is assumed to be particle in nature. Which was unable to explain the deBroglie' hypothesis or the uncertainty principle and has certain demerits.

The uncertainty principle reveals the wave nature of the electrons or electron clod model. The Bohr condition of a stable orbits of the electron can nicely be explained by the electron cloud model, the mathematical form of which is λ = nh/mv, where, λ = wavelength, n is the integral number, h = Planck's constant, m = mass of the electron and v = velocity of the electron.

The integral number i.e. n is similar to the mathematical form of Bohr's atomic model, which is mvr = nh/2π. (r = radius of the orbit).

Thus, the electron cloud model is an extension of the Bohr atomic model, which can explain the demerits of the Bohr model. Later it is revealed that the electron have both particle and wave nature. Which is only can explain all the features of the electrons around a nucleus of an element.
