Were noble gases shown in the periodic table of 1869?
No, noble gases were not shown in the periodic table of 1869 because they were not discovered until late 19th and early 20th centuries. Helium was the first noble gas to be discovered in 1895, followed by other noble gases such as neon, argon, krypton, and xenon.
What distinguishes noble gases from other nonmetals?
Unlikely other elements in the periodic table, noble gases rarely form compounds with other elements.
What is the family name for neon on the periodic table?
Neon is a noble gas located in period 2 on the periodic table.
Elements that do not typically react with other elements are known as?
Elements in the Periodic Table that are not reactive are called the Noble Gases.
Why couldn't Mendeleev predict the existence of the noble gases in the periodic table of elements?
Mendeleev couldn't predict the existence of noble gases because they are inert and do not readily form compounds with other elements. Mendeleev's periodic table was based on the properties of elements and their compounds, and since noble gases do not readily form compounds, they did not fit into his classification scheme.
How did Dmitri Mendeleev discover the periodic table with noble gases?
Dmitri Mendeleev did not discover the noble gases as they were not known at the time he created the periodic table. The noble gases were discovered later by other scientists. Mendeleev's periodic table focused on arranging elements by atomic mass and properties to show periodic trends.
Which element are not noble gases?
Elements such as oxygen, hydrogen, carbon, and nitrogen are not noble gases. These elements are found in different groups of the periodic table and have varying chemical properties compared to the noble gases.
Are noble gases stable elements in the periodic table?
Yes, noble gases are stable elements in the periodic table because they have a full outer electron shell, making them less likely to react with other elements.
What is found on the right of the periodic table?
The column all the way to the right of the periodic table indicates noble gases. Noble gases have their outermost orbit completely filled with electrons so these gases do not react with other things very easily. Some examples of noble gases are helium, radon, xenon etc.
Noble gases have less stable electronic configurations then all other elements in the periodic table?
Noble gases actually have the most stable electronic configurations in the periodic table due to having a full outer shell of electrons. This full octet makes them less likely to react with other elements, earning them the name "noble gases."
What family of elements was originally left out of the periodic table?
The noble gases, column 18 in the most common modern periodic table.
What family is group 18 on the periodic table of elements?
Group 18 on the periodic table contains the noble gases, also known as the inert gases. This family includes helium, neon, argon, krypton, xenon, and radon. They are colorless, odorless gases with very low reactivity.
