How many elemets were in the periodic tabel in 1834?
There were around 52 known elements in the periodic table in 1834. The periodic table was still in its early stages of development during this time, and many elements were discovered and added to the table in the years that followed.
What group of elemets will most likely form an ion with a -1 charge?

Which side of the periodic table do elements gain valence electrons?
all the elemants have valence electrons the last number of the elecotrons is the elemets valence electrons
What are elemets that are all unreactive gases that tend not to combine with other elements known as?
Those gases are called noble gases. They are i the 18th group of the periodic table.
Why are the elemets in the periodic table listed in ceratin groups?
The vertical "groups" group elements by chemical properties the horizontal "periods" group elements by the number of energy levels
How is the elements on the periodic table of elemets arranged?
Groups 1-12 are metals 1-2 are the alkaline and alkaline earth metals, 3-12 are the transistion mrtals and.13-18 are nonmetals.
Where on the periodic table are you most likely to find elements that do not react with other elemets?
Elements that do not react with other elements are typically found in the noble gases group, located in Group 18 of the periodic table. These elements have full outer electron shells, making them stable and unlikely to form chemical bonds with other elements.
What is the name of the table of elements?
