<em>n</em> = 15. A Bohr orbit with <em>n</em> = 15 comes closest to having a 24 nm diameter
.
The formula for the radius <em>r</em> of the <em>n</em>th orbital of a hydrogen atom is
<em>r</em> = <em>n</em>^2·<em>a</em>
where
<em>a</em> = the Bohr radius = 0.0529 nm
We can solve this equation to get
<em>n</em> = √ (<em>r</em>/<em>a</em>)
If <em>d</em> = 24 nm, <em>r</em> = 12 nm.
∴ <em>n</em> = √(12 nm/0.0529 nm) = √227 = 15.1
<em>n</em> must be an integer, so <em>n</em> = 15.

Explanation:
Answer. One of the key components of the softgel capsule is the plasticizer used to make the shell elastic and pliable and to minimize brittleness and cracking. The plasticizer usually accounts for 20-30% of the wet gel formulation which can impact the quality of the finished product.
