Answer:
In half it would go twice as far but the effect of lost kinetic energy is lessened.( I could be wrong)
Salt is a mixture,salt is composed of sodium and chlorine,NaCI.Its a compound of two distinct elements that can not be broken down further without changing the properties of the substance.(I hoped that helped)
Because they are no longer attracted to electron - poor reaction sites , and because they reverse their dipole moments , also they lost molecular geometry that enables nucleophilicity which no longer have a lone pair of electrons.
<u>Answer:</u> The correct answer is Aufbau principle.
<u>Explanation:</u>
Pauli exclusion principle states that no two electrons with in an atom can have all four quantum numbers same.
Heisenberg principle states that it is impossible to measure with high precision the value of momentum and position of an electron.
Aufbau principle states that the electron will occupy the lowest energy level first before occupying the higher energy levels.
Schrodinger equation is used to find the allowed energy levels of quantum mechanical systems of an electron.
Chromium is the 24th element of the periodic table and its electronic configuration must be written as:
But the actual configuration for this is
This configuration is an exception to Aufbau's principle because half filled sub-levels is more stable than other configurations.
The actual configuration has half filled 'd' and 's' sub-levels but the expected configuration had fully filled 's' orbital and partially filled 'd' orbital.
Thus, actual configuration is accepted for chromium atom.
Hence, the correct answer is Aufbau's principle.
