Explanation:
Part of life is the role we certainly play during our role in life.Like a quote of shakespeare,we have our roles in earth to perform or we are like a chess whom we don't want to waste a move.
Art of life signifies that our life is wonderful with mysteries and hypotenic beauty and wonders and with different moments in a journey.

Answer:
The electrons that participate in chemical bonds are the valence electrons, which are the electrons found in an atom 's outermost shell.
Explanation:
The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct did not give the results described and is denoted as option A.
<h3>What is Thomson “plum-pudding” model?</h3>
This model was proposed by J.J Thomson in which referred an atom as a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.
This model was incorrect and the Rutherford atomic model was adopted in which he described the electrons orbits about a tiny positive nucleus.
The nucleus contains protons and neutrons instead thereby making it the correct choice.

The options include the following:
a.The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct.
b.The Rutherford experiment was useful in determining the nuclear charge on the atom.
c.Milikan’s oil-drop experiment showed that the charge on any particle was a simple multiple of the charge on the electron.
d.The electric discharge tube proved that electrons have a negative charge
When an electron transit from lower level to higher level it emits energy
When an electron transit from higher level from a lower level it absorbs energy
n=3 to n=5, : absorption
n=1 to n=3, : absorption
n=3 to n=2, : emission
n=2 to n=1 : emission
the highest energy means highest wave number
wave number = Rh (1/ n1^2 - 1/n2^2)
Rh = 1.1 X 10^7 m^-1
1) n=3 to n=5
wavenumber = Rh ( 1/ 9 - 1/ 25) = 0.071 Rh
2) n=1 to n=3
wavenumber = Rh ( 1- 1/9 ) = 0.89 Rh
3) n=3 to n=2
wavenumber = Rh ( 1/4 - 1/9) = 0.139 Rh
4) n=2 to n=1
wavenumber = Rh ( 1- 1/4) = 0.75 Rh
Thus for 2) n=1 to n=3 energy will be maximum
