When a hydrogen atom makes the transition from the second excited state to the ground state (at -13.6 eV) the energy of the phot
viktelen [127]

Answer : The energy of the photon emitted is, -12.1 eV

Explanation :

First we have to calculate the 'n^{th}' orbit of hydrogen atom.

Formula used :

E_n=-13.6\times \frac{Z^2}{n^2}ev

where,

E_n = energy of n^{th} orbit

n = number of orbit

Z = atomic number  of hydrogen atom = 1

Energy of n = 1 in an hydrogen atom:

E_1=-13.6\times \frac{1^2}{1^2}eV=-13.6eV

Energy of n = 2 in an hydrogen atom:

E_3=-13.6\times \frac{1^2}{3^2}eV=-1.51eV

Energy change transition from n = 1 to n = 3 occurs.

Let energy change be E.

E=E_-E_3=(-13.6eV)-(-1.51eV)=-12.1eV

The negative sign indicates that energy of the photon emitted.

Thus, the energy of the photon emitted is, -12.1 eV

An atom of argon has a radius rar = 88 pm and an average speed in the gas phase at 25°C of 172 m/s.
Rudik [331]

Answer:

1.2* 10³ rNe.

Explanation:

Given speed of neon=350 m/s

Un-certainity in speed= (0.01/100) *350 =0.035 m/s

As per heisenberg uncertainity principle

Δx*mΔv ≥\frac{h}{4\pi }

4π

h

..................(1)

mass of neon atom =\frac{20*10^{-3} }{6.22*10^{-23} } =3.35*10^{-26} kg

How many σ and π bonds are present in a molecule of cumulene? (figure 1)
Harlamova29_29 [7]

Three double bonds and four single bonds, or 3(+)+4=7+3, are present in cumulene.

Sigma bond between the hydrogen and carbon on the end-side of the cumulene is visible. Carbon and hydrogen are linked by a total of four sigma bonds. Carbon is joined to carbon in the center by 3 sigma bonds and 3 pi bonds. Cumulene now has a total of 7 sigma bonds and 3 pi bonds. A cumulene is a molecule in organic chemistry that has three or more cumulative (consecutive) double bonds. sp2 hybrid orbital of C overlapping with 2p orbital of O and one bond make up the bond.

In the case of compounds with two bonds, one bond is a sigma bond and the other is a pi bond. A triple bond indicates that the chemicals.
