The principal quantum number (n): specifies the principal shell of the orbital.
The answer is option D.
The important quantum number (n) describes the dimensions of the orbital. Orbitals for which n = 2 are larger than those for which n = 1, as an example. Because they have got opposite electric costs, electrons are interested in the nucleus of the atom.
The numerals, called essential quantum numbers, imply strength degrees as well as the relative distance from the nucleus. A 1s electron occupies the energy stage nearest the nucleus.
A 2s electron, less strongly certain, spends most of its time farther far from the nucleus.

<u>Answer:</u> The isotopic symbol of unknown particle is
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given fission reaction:
<u>To calculate A:</u>
Total mass on reactant side = total mass on product side
228 = A + 224
A = 4
<u>To calculate Z:</u>
Total atomic number on reactant side = total atomic number on product side
90 = Z + 88
Z = 2
Hence, the isotopic symbol of unknown particle is
