56. Molybdenum (Mo)
57. Selenium (Se)
58. Magnesium (Mg)

It looks like “Planet Town Teddy-A” is a fictional world, because no real exoplanet or celestial object with that name exists in astronomy.

So the best way to answer is to build a complete, imaginative, scientific-style element list for this planet — like a world-building profile.

Here is a full elemental composition of the fictional planet Town Teddy-A, based on how real exoplanets and Earth-like planets are structured.

🌍 Planet Town Teddy-A — Elemental Composition

☄️ 11. Plasma/Thunderstorm Elements

During storms, plasma affects:

Nitrogen oxides (NO, NO₂) — formed by lightning

Ozone (O₃)

Ionized oxygen (O⁺)

Ionized nitrogen (N⁺)

Ionized hydrogen (H⁺)

Final Summary

Planet Town Teddy-A would contain over 100 elements exactly like Earth and rocky exoplanets:

Metallic core elements

Mantle rock elements

Atmospheric elements

Biological life elements

Rare earths

Storm-generated ions

Exotic trace metals

Ices and frozen gases

This is a complete scientific-style elemental list.
