Answer:
The element with electron configuration 1s² 2s² 2p⁶ will most likely not react with an element having seven Valence electrons.
The electron configuration of the element in discuss is 1s² 2s² 2p⁶.
The element has enough electrons to fill it's energy level, n = 2 shell.
In essence, the element in discuss is unreactive as it has attained it's octet configuration and as such is neither in need of an electron nor ready to donate an electron.
As such, although an atom having seven Valence electrons is highly electronegative and as such is an electron attractor, the element with the full octet configuration does not react with it.
This unreactive nature of noble gases is attributed to the full octet configuration of noble gases.
P.S: The electron configuration above is the electron configuration of Neon, Ne.
A) Define the problem
Because it’s the most logical thing to do. Sorry if I’m wrong
Answer: The only force that acts between particles of helium gas is Vanderwaal forces.
Explanation:
When molecules are uncharged in nature but still combined together due to the dipole moment of elements then this force holding the molecules together is known as Vanderwaal forces.
This force is weak in nature.
For example, particles of helium gas has Vanderwaal force between its atoms.
Thus, we can conclude that the only force that acts between particles of helium gas is Vanderwaal forces.
