No. An element, by definition, does not contain any other element. The only element that contains carbon is carbon; however, carbon does make compounds with other elements - for example, carbon dioxide and carbon monoxide with oxygen.
All of them tend not to react with each other until you get lower down the group
No, "oxygeon" is not an element. Oxygen, on the other hand, is an element that is represented on the periodic table by the symbol "O" and has an atomic number of 8.
An element.
No, the first element on the Periodic Table is Hydrogen, but because of its unusual behaviour it is usually placed by itself, not next to any other elements. The second element is Helium.
Mercury is an element, represented by the symbol Hg on the periodic table. It is a metal that is found in nature as a pure substance and does not need to be chemically combined with other elements to exist.
No. An element, by definition, does not contain any other element. The only element that contains carbon is carbon; however, carbon does make compounds with other elements - for example, carbon dioxide and carbon monoxide with oxygen.
On the periodic table, the elements fall into groups (the vertical columns) which are often called families. The reason is that elements in a group are chemically similar to each other.

Fluorine is sometimes called the hungry wolf of the periodic table because it is the most reactive element.
Bromine is chemically reactive. It is a halogen element, part of Group 17 in the periodic table, known for its reactivity with other elements. It readily forms compounds with metals and nonmetals.
No, "oxygeon" is not an element. Oxygen, on the other hand, is an element that is represented on the periodic table by the symbol "O" and has an atomic number of 8.
An element.
No. helium is chemically inert and does not combine with other elements.
There are more metals than any other type of element in the periodic table.
The Periodic Table was invented by Dmitry Mendeleyev. He grouped every known element and he used this table to predict the existence of other several elements. Mendelevium name pays homage to Dmitry Mendeleyev.
Noble gases, group 18 on the periodic table, do not react readily with other elements due to their stable and full outer electron shells. This leads to low reactivity and makes them chemically inert.
