Are there chemical elements in our planet that we don't know of?

Certainly not. The periodic table is completely full. All the additions to it after element number 92 have been man-made, and so will be any more after 118. Besides all of the elements after 99 are gone shortly after they are made.
If you want to discover unknown things, look for new compounds. There are limitless numbers of compounds to be found, both natural and man-made.

We do not know many things, no matter how much human beings boast about their genius, it will not change the fact that God created the world and only he knows the secrets it hides OK?
Good afternoon and stay with God 🙏😉 my first good afternoon of the day hehe

let's start here.
"elements" is a method for sorting out atoms that are different from one another. Different by the number of protons in their nucleus.
"periodic table" is how we organize elements by similar chemical properties.
the list of POSSIBLE elements is infinite. So a periodic table is infinite. Take a look at this ptable
notice a couple of things
.. (1) the actinide and lanthanide series are in their correct places
.... ... we typically show them below the main table to fit everything on
.... ... an 8 1/2 x 11 page, but this is how it should be shown
.. (2) this table shows through element 173
.. (3) some elements have 1 or 2 letter "familiar" symbols
.. .. . while others have 3 letter symbols like Uuo, Uho, etc
Those elements that have been "discovered" meaning have been isolated in a lab somewhere are given real names with 1 or 2 letter symbols. Those elements that are not yet "discovered" (not yet isolated in a lab) are named according to their atomic number. Uuo is Un Un Octium.. 1 1 8. likewise, Uho is Un Hex Octium. 168. If atoms of those elements are someday "discovered", they will be assigned a real name with a 1 or 2 letter symbol
back to your question.. (and a few others I added)
.. "are there chemical elements on our planet that we don't know of"?
.. "no. We have a method of naming ALL chemical elements whether
.. .they have been discovered or not by the number of protons in their
.. .nucleus. Since chemical elements are sorted by the # of protons,
.. .we at least know some information about ALL elements"
.. "have all elements here on Earth been discovered"
.. "look at this periodic table. https://ptable.com/ all the elements with
.. known stable atoms have the atomic mass shown without ( ). All the
.. elements with unstable atoms have atomic mass shown in ( ). See
.. the difference between Pb and Po for example. Elements with stable
.. atoms are naturally occurring here on Earth. SOME of the elements
.. that have only unstable atoms (to our current knowledge) are found
.. here on Earth, but most of those unstable elements are produced
.. in labs or nuclear reactors / bombs and are not naturally occurring.
.. "what elements had the Uuo type designation are are now discovered"?
.. "see elements 113 - 118".. they have recently been discovered and named
.. "will atoms of other elements higher than 118 eventually be discovered"
.. "elements with 119 and above protons in their nucleus are certainly
.. possible but with higher and higher nucleons (protons and neutrons)
.. .atoms tend to be more and more unstable. Yes, we'll find more in
.. .labs. Yes, they will probably be short lived and decay rapidly. Yes
... it's possible a few might even be somewhat stable. It is UNLIKELY
.. .any atom with > 119 protons will be found naturally occurring on Earth.

Noble gases (right column, red) are known to be chemically non-reactive and do not naturally bind to other atoms to form molecules on Earth. But it's a different story in space. In the past ten years, astronomers in space have discovered two examples of chemical compounds made from noble gases helium and argon.

No. .... All of the possible spaces in the periodic table have been filled with known elements up through Z=118, and all the elements from neptunium (Z=93) on up are synthetic for the most part. There are traces of a few of these elements, but they only occur briefly as a result of natural processes before they decay into other elements.

anything is possible

That's a extremely tough question to answer. I would have to say yes.. If for some odd reason a big asteroid slams into the earth with that new element, that may be a possibility. If we do find one, I'm sure it might be extremely rare.

No. But humans have made some that do not exist in nature.

The element would have to have at least 119 protons. It’s unlikely, but possible. I would say there’s a high probability of such an element somewhere else in space though.
