Answer:
The change in energy when a neutral atom in the gaseous state adds an electron to form a negative ion.
Explanation:
That is, it is the energy involved in the reaction
X(g) + e⁻ ⟶ X⁻(g)
For most elements, the electron affinity is negative.
However, there are two major exceptions — the values are positive for the elements of Groups 2 and 18 (note the troughs in the graph below).
Below is the structure of 3-Methylpentane. The word pentane in name specifies the parent chain which ends on -ane (alkane) and pent- shows number of carbon atoms is parent chain (pent=5). The position of substituent is specified at the start i.e. 3.
Using PV=nRT
you get 268.976268L
=270L
Imagine A is a Heterogeneous mixture because it a mixture composition that does not stay the same throughout the mixture.
Imagine B is the Homogeneous mixture because it has no changes or irregularities
For emission n=3 to n=1 The energy will be released
When an electron transitions from a lower state of energy energy level, absorption spectra are formed. When an electron transitions from a higher energy state to a lower energy state, emission spectra are produced.
To see a wavelength released, electrons would have to go down energy levels to view an emission spectra, limiting our solution options to And because n=3 to n=1 has more energy emitted than n=2 to n=1, the one with more energy emitted will have a shorter wavelength because wavelength and energy are inversely related. Energy will be released as an electron transitions from a higher energy state 3 to a low energy state 1.
