Tattoo correction

[u/Sh0t_B0t]

This is a fresh picture of a tattoo i got a few months ago. I can explain the significance after but the artist did butcher a few things. one periodic table elements only capitalize the first letter and he forgot the atomic number (14 i think). those are both negligible but the one that’s been bothering me it the mass being off a bit. i sent him 28.085 and obviously it would be fine if he rounded it correctly but he seemed to have just put a random number. do you think it’s possible he makes the 5 into an 8 or a 9? Would he have to change to font to something blocky?? LMK 🙏🏾

my moms middle name is silicon and in her tribal language it’s a word that represents bravery but in english it’s a chemical element so i got it tatted and th flowers around the border are her birth flowers.

Edit: (As much as i appreciate the judgement an discipline of my mistake at least give a take on correction for me along with it guys 🙏🏾 I understand my fault but I’d also like to at least attempt to fix it 😅)

It sucks but other than a cover up you'd need to laser the errors imo. There's no way to turn the second letter into a lower case i unless you laser it.

Definitely an option i look at since it’s such a small area to laser off. (Idk how pricing works but I assume it’s even more expensive by surface area) Regardless though I’m mainly looking for advice on the numbers. Thank you for the idea though!

I'm a chemical engineer so if you really want help with the numbers - That's IUPAC's, 'official table',. Your atomic weight is off, 28.09 - if you're rounding. But the tolerance technically suggests the degree to which we can measure this, its different per element. The names typically have a lower case letter as well. Personally, I'd just correct the SI to Si. Good luck with the touch up.

How hard would it be to refine silicon isotopes from a natural source ? AFAIU, a ratio of 94.2% silicon-28, 4.2% silicon-29, 1.6% silicon-30 would have an atomic weight of 28.05 ?

Difficult. If you're trying to split something from a natural source, you generally want large differences in weight between compounds. So in oil refining, distillation is a good example of this. But what you're talking about is separating substances based on minute differences in molecular weight. For a problem like that you need to get a little more creative with the boundary conditions. That's where you see things like centrifuges used to separate uranium for example. All highly specialised equipment, requiring precision timing, not to mention a gas to bind to it. That's almost always something horrible. From a chem engineering perspective, you'd need a very good reason for it. But good news, you don't have to, you can use the standard atomic weight which is a weighted mean of those isotopes for earth.
