Answer: Option (d) is the correct answer.
Explanation:
An orbital is defined as the energy shell which can contain a maximum of two electrons with opposite spins.
A wave like behavior of an electron is determined by an orbital and basically an orbital acts like a mathematical function.
For example, in a p-sub shell the orbitals present are 
, 
and 
.
Therefore, we can conclude that orbitals are defined by energy level.
Answer:
Explanation:
<u>1) Data:</u>
a) V₁ = 38.2 liter
b) P₁ = 91 psi
c) V₂ = 77.4 liter
d) P₂ = ?
<u>2) Formula:</u>
According to Boyle's law, at constant temperature, the pressure and volume of a fixed amount of gas are inversely related:
- PV = constant ⇒P₁V₁ = P₂V₂
<u>3) Solution:</u>
- Solve for the unknown: P₂ = P₁V₁ /v₂
- Substitute the values: V₂ = 91 psi × 38.2 liter / 77.4 liter = 44.9 9si ≈ 45 psi.
To find the wavelength of an electromagnetic wave for the given frequency can be determined by using the formulaSpeed=Wavelength x FrequencyWavelength=Speed/FrequencyGenerally Speed of the electromagnetic wave is 3x10^8 m/sBy substituting the values Wavelength=3x10^8 m/s / 2.63x10^12 s^-1Wavelength=1.14 x 10^-4 metres
Bohr's theory states that the motion of the electron (particle) around the nucleus is very much similar to motion of the planets around the sun in the solar system. Both in the mathematical and physical sense.
The Bohr's Atomic theory only explains the motion of the electrons in discrete atomic orbitals that are predicted by the Bohr's equation.
It strictly implies that the electron only exists in these discreet orbitals and fails to explain anything about the nature of the electron in between the discrete orbitals.
The modern atomic theory does not share this limitation as it does not impose the electron to only occupy the discrete orbitals and neither does it impose particle nature upon the electron.
In the modern theory does not focus on describing the motion of the electron around the orbital but rather the probability of finding an electron around the nucleus. The modern atomic orbitals or electron clouds are the regions in which the probability of finding the electron is the highest when the wave function collapses. The Schrödinger's wave equation explains the evolution of the wave function in time. Hence enabling us to predict the future possible locations of the electron but never the exact location as that is impossible due to the Heisenberg's Uncertainty principle.
