Honestly, this doesn't look good :/

I was waiting to see if anyone else would comment on part 6 but I only got two, one from u/ComedyGold13 (I'll call them Comedy) and another that didn't convince me, besides, Comedy had already suggested the same thing before

These are the new plants

Levitater-Livermormium (Comedy): For two reasons, they sound similar and levitater was first created in collaboration with the JINR lab in dubna, the same one behind teleportato's placement. makes a little sense for the potatoes to have some kinda connection. pretty weak overall but thats to be expected with the artificial elements

Bloomerang-Aluminium (Comedy): (since we hate hot potato so much, sigh) bauxite, aluminum ore is found primarily in australia. 

Iceweed-Mercury (Comedy/Me) A metalic plant that spreads out over the ground, like a liquid. Also, although Comedy considered using Spikerock, I thought Iceweed was a better choice because mercury has a low melting point

Spikerock-Zirconium (Me): Zirconium becomes trapped in surface stones and sand because it is difficult to erode due to its resistance; furthermore, Spikerock is composed of rocks

In case you're wondering, there are also some plants that occupy the same square or many squares, but this is just a concept that's not yet clear, because the elements share similar characteristics and I hadn't found any differences (they're in gray)

Chomper-Carbon (Me): This was an idea I'd had for a while, but I hadn't included it yet because carbon is in everything. Basically, it was about the amino acids, vitamins, and carbohydrates that use carbon and are the building blocks of food

Seedling-Carbon (u/dTrecii): Since carbon was the basis of life, it was obvious that a seedling would be used, although its ability in PvzH is a bit broken and that's why I didn't include it to respect the balance as you progress through the chart

Laser Bean-Yttrium and some Lanthanides (Me): These elements are used for fiber optic lasers, just as Laser Bean shoots lasers from the eyes

Ghost Pepper could be key for the Super Heavy items, which don't last very long

Other candidates for some elements would be Power Lily for the f-block and Ultimatum for other Lanthanides

And yes, you saw it, Magnifying Glass may become Lanthanide because Lanthanides are used for sophisticated glass for specific functions like sunglasses or glasses of various colors, thus leaving Silicon for other plants like Spikeweed that are placed in the soil and which the soil uses silicon as its main element
