NH3 is the chemical formula of the compound ammonia. The Periodic Table lists elements and not compounds.
What else can I help you with?
How many elements are included on the modern periodic table?
There are 117 elements on the periodic table, however, there is one blank spot that lies on the periodic table of elements, it has the atomic number of 117. If it were discovered, there would be 118 elements on the periodic table of elements.
When new elements are placed into the periodic table what happens?
If new elements are placed, then they would be appended in the periodic table. It won't disturb existing periodic table.
What is one characteristic on the periodic table that is not periodic?
My answer for this would be Colour of the elements.
What element in the periodic table is similar to sulfur?
Elements in the periodic table that are similar to sulfur would be oxygen, and selenium
How would you categorize most of the elements on the periodic table?
Elements and atomic number
What is CuL2 in the periodic table?
CuL2 is not found on the periodic table as a stand-alone element. It likely refers to a compound where Cu represents the element copper and L represents a ligand that is attached to the copper atom. This compound would be a coordination complex, not an individual element on the periodic table.
Why did mendeleev leave blank spaces on his periodic table?
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
What did Dmitri Mendeleev arrange into a systematic chart?
Dmitri Mendeleev arranged the known chemical elements into a systematic chart known as the periodic table. His arrangement was based on the elements' atomic mass and chemical properties, leading to the organization of elements in periods and groups. Mendeleev's periodic table laid the foundation for the modern understanding of the relationship between elements.
What was true about the elements that would later be put in those gaps?
When Mendeleev proposed his periodic table, he noted gaps in the table, and ... Initial versions of the periodic table did not give the rare earth elements the ... that these atomic elements would be discovered, that he included them in later.
What does NO mean on the periodic table?
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.
How would the periodic table look if the lanthanide actinide series were in their proper place?
Periodic table would be complex then. It will make study of elements difficult.
What are the empty spaces in the periodic table meant for?
It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.
