The elements which were not discovered at that time were made blank. Mendeleev named them as eka-aluminium, eka-silicon etc. They were discovered later and were placed in the gaps.
there is no such thing as drive on the periodic table
No - Ba is from the periodic table though.
An element is a substance that cannot be broken into simpler substances by chemical methods, such as Neon or Oxygen.The periodic table contain all known chemical elements.
Not true I am trying to find the same thing out but I no for a fact they are both on a periodic table.
There is no element labeled "Zu" on the periodic table. If you're looking for an element symbol, it may not exist in the current periodic table. If you provide more context or details, I may be able to help you further.
There is no difference between "period table" and "periodic table" - they refer to the same thing. The periodic table is a tabular display of the chemical elements organized by atomic number, electron configuration, and recurring chemical properties.
The only thing it might mean would be number, but that is usually no. and not NO. NO would be nitrogen oxide (nitric oxide), but that would NOT appear in the periodic table, as it is a compound, and only ELEMENTS appear in the periodic table.
Generally the atomic mass
==Yes== Hydrogen, a gas, is found on the left side of the periodic table. And it depends on which periodic table you look at. The standard 18 column ones have hydrogen on the left, but, a geologists' periodic table may have more (sorry, I'm not a geologist, I just know there is such a thing). But I think you mean the everyday periodic table... So yes, hydrogen.
it is an element in the periodic table and can be used to science related thing.

The periodic table is a list of all of the known elements that make-up everything in the universe. Metal is made of those elements, just like every thing else.
