What are the elements that make a seven on the periodic table?
What are the elements and what is special about them? My teacher was teaching this today and I missed it. Please help!
Answer:
they are the diatomic elements along with hydrogen. they are nitrogen, oxygen, fluorine, chlorine, bromine, and iodine
Can you be more specific on where on the periodic table you are talking about. Left or right? top or bottom? number at the top of the column? number at the left of the period?
If you are talking about column 7, which on the new periodic tables is 17, they are called halogens, and are very active nonmetals.
The Group 7 elements.
Any of five nonmetallic elements — fluorine, chlorine, bromine, iodine, and astatine — with similar chemical properties. They occur in the second rightmost column of the periodic table as usually arranged. All are highly reactive oxidizing agents (see oxidation-reduction) with valence 1 (for fluorine, the only valence). They combine readily with most metals and nonmetals to form a variety of compounds and never occur uncombined in nature. A radioactive element, astatine occurs naturally in minute amounts as an intermediate decay product; it has no stable nonradioactive isotopes. Halogen salts formed with metal atoms (halides) are very stable; sodium chloride is the most familiar. The halogen lamp takes its name from the halogens included in the gas within its tungsten-filament bulb, added to prolong filament life and increase brightness.
These would be: N2, O2, F2, Cl2, Br2, and I2.
They all exist in diatomic form.
