Explanation:
₁₄Si 1s²2s²2p⁶3s²3p².
Principal quantum number (n=3) have four electrons (3s²3p²).
2) ₁₉K 1s²2s²2p⁶3s²3p⁶4s¹.
Azimuthal quantum number (l=o) have seven electrons (1s²2s²3s²4s¹).
3) ₈₀Hg [Xe] 4f¹⁴5d¹⁰6s².
Principal quantum number (n=4) have thirty-two electrons (4s²4p⁶4d¹⁰4f¹⁴).
The principal quantum number is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state.
The azimuthal quantum number is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital.
Answer:
Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical changes can be undone, if energy is input.

<u>Answer:</u>
<em>The basic theme behind the movie interstellar on which it is based is the theory of relativity that was suggested by Einstein.</em>
<u>Explanation:</u>
As per <em>Einstein theory</em> the twin sister theory explains, how time is relative in nature that if two sisters war twins one of them remains behind. And other travels in space after a certain <em>ears cap the one thing on earth would age. </em>
While the other would not the same theory was followed in the movie. And the main cast of the movie who was the hero did not age while his daughter ages with respect to time so when the meet her daughter is much older than him.
<em>The movie also shows the theory behind black holes and how it feels inside the black hole.
