Answer:

Option c: Possible electron energy states are quantized within an atom.

Explanation:

The Bohr's Model of the hydrogen atom consisted of the movements of the electrons around the positively-charged nucleus in circular orbits that have a certain energy state. The energy of that orbit is given by:  

E_{n} = - \frac{Rhc}{n^{2}}

<em>Where:</em>

E(n): is the energy of an electron in a particular orbit

R: is the Rydberg constant

h: is the Plank constant

c: is the speed of light

n: is a positive integer which corresponds to the number of the orbit

The ground state energy of a electron in the hydrogen atom is equal to -13,6 eV.

Bohr's Model aims to propose that the electron is restrictedly to occupy a certain region in the atom.    

Therefore, the conclusion of Bohr after observing emission spectrum lines is that "possible electron energy states are quantized within an atom", so the correct option is c.

I hope it helps you!

A soft silvery metal has two naturally occurring isotopes: mass 84.9118, accounting for 72.15% and mass 86.9092, accounting for
zloy xaker [14]

Answer: The atomic weight of the metal would be 85.47.

Explanation:

Mass of isotope 1 of metal = 84.9118

% abundance of isotope 1 of metal = 72.15% = \frac{72.15}{100}

Mass of isotope 2 of metal= 86.9092

% abundance of isotope 2 of metal = 27.85% = \frac{27.85}{100}

Formula used for average atomic mass of an element :

\text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})

A=\sum[(84.9118)\times \frac{72.15}{100})+(86.9092)\times \frac{27.85}{100}]]

A=85.47

Therefore, the atomic weight of the metal would be 85.47.

mickey reacts magnesium with 1.0 M of hydrochloric acid. the reaction tales 2 minutes and 34 seconds to complete. what are 2 way
lutik1710 [3]

Answer:

Explanation:

To slow down this reaction, we can use any of the methods listed below:

  • Increase the size of the magnesium by using solid lumps of  the metal. This will take a much faster time to react than powered and granulated magnesium.
  • Reduce the concentration of the acid.
  • Let the reaction take place at a much lower temperature than that given.

These conditions will slow down a chemical reaction.
