Answer:
elements in same group have same valence electron.
period of element is equal to valence shell
Explanation:
if the elements are in a same group then they will be having same number of valence electron.
the period of an element in periodic table is equal to the valence shell of the element. that is if the valence electron are in 3 rd shell then the element will be in third period.
Answer:
Explanation:
For a chemical reaction, equilibrium is a state at which the rate of the forward reaction equals that of the reverse reaction. The equilibrium constant Keq is a parameter characteristic of this state which is expressed as a ratio of the concentration of the products to that of the reactants.
For a hypothetical reaction:
xA + yB ⇄ zC
The equilibrium constant is :
The given reaction involves the decomposition of H2O into H2 and O2
The equilibrium constant is expressed as :
Since Keq = 5.31*10^-10
Answer:true
Explanation:
The neutrons and the protons are what stay there
We have that the statement of Bohr's model understanding of electron energy levels is True
Option A
<h3>Electron energy levels</h3>
Generally, Bohr's model in his famous publication saw to explaining where <em>electrons</em> could be found. The model also explains the properties of different elements.
Therefore, The statement "A major advancement of from the Bohr model of the atom was the understanding of electron energy levels." is
True
