What are diaatomic elements?
Diatomic elements are unique because they are the only seven elements that, when the atoms are under normal conditions in the elemental state, form pairs of atoms. Most elements are organized into crystalline structures, like metals, metalloids and solid nonmetals, or lone gaseous atoms, like the noble gases. Hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine and bromine form H2, N2, O2, F2, Cl2, I2, and Br2, respectively. They are also all of the elements that are non-noble gases at normal pressure and temperature, with the exception of bromine, which is a liquid.
Why are noble gases the only unreactive elements on the periodic table?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Why are Group 8A elements known as noble gases?
The grup 8 elemnts are quite unreactive- the term noble was I think coined for gold and other unreactive metals- and the adjective got re-used- they were once called the inert gases- but this is no longer true as unstable reactive compounds have been made for Argon and the heavier members of the group.
Substance that cannot be changed into a simpler substance under normal laboratory conditions?
Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.
Why are noble gases considered to be unreactive?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Sulfur is often found in nature as an element not combined with other elements in a compound What does this fact tell you about the reactivity of sulfur?
Sulfur is relatively unreactive with the constituents of the Earth's atmosphere and crust under normal conditions. (However, sulfur can react with many of these materials under favorable conditions.)
Simplest form of matter that can exist under normal conditions?
Elements
Which element is a gas that does not combine with other elements?
The noble gases in group 18 of the periodic table do not usually form compounds with other elements. Under very unusual circumstances in the laboratory, chemists have forced many of these elements to actually make compounds but none of the noble gases make compounds under normal conditions.

What are the four regions of the periodic table?
The regions or sections of the periodic table of elements are, the metals, the transition state elements, the nonmetals, the noble gases, and underneath those regions, the lanthanide series and the actinide series. Hydrogen is sometimes placed above all the other sections, by itself. Technically it is a metal (even though it does not look like one under normal conditions). It has a single valence electron.
What element readily sublimates under normal conditions?
Iodine is one of the easiest elements to sublimate.

What state of mater are most nonmetals?
Most non-metallic elements are gases. They include all the noble gases (group 18), fluorine and chlorine in group 17, oxygen, and nitrogen. Under normal, familiar conditions, bromine is a liquid, and sulfur, selenium, phosphorus, and iodine are solids. Anything not mentioned is either a metal or a metalloid.
What is the name and symbol of all elements on the periodic table that exists as liquids in normal conditions?
mercury (Hg) and bromine (Br)
