Mono isotopic elements are stable isotope of an element.From 80 isotopic elements there are 26 radioactive elements discovered up till now.These mono isotopic may or may not be radioactive if they are radioactive they have halve lives.

What are some Elements with hydrogen and oxygen?
Hydrogen and oxygen are already elements. Elements do not contain other elements.
Hydrogen and chlorine are pure substances or chemical elements?
they are chemical elements
What kind of elements are halides oxides sulfates sulfides carbonates and native elements?
What you have listed are not elements (except for the 'native elements'), they are classifications of minerals.
What Elements on the left side of the table are classified as what type of elements?
Group 1 Elements (elements in the first group [column]) are classed as Alkali Metals. Group 2 Elements (elements in the second group [column]) are classed as Alkaline Earth Metals. All elements not in a representative group are classed as Transition Metals. Group 3 Elements (elements in the third full group [coulumn]) are classed as Earth Metals
What are uncontrollable elements?
Elements that cannot be controlled.
How many elements in the periodic table are monoisotopic?
20 ELEMENTS He,Be,Na,Al,P,Sc, Mn,Co,As,Y,Nb Rh,I,Cs,Pr,Tb Ho,Tm,Au,Bi,TH
What is the percent composition of beryllium?
Beryllium is a monoisotopic chemical element.
Is an element a physical or chemical change is it homogeneous or heterogeneous?
A chemical element is homogeneous only if it is monoisotopic; but in practice this aspect is neglected. A chemical element is not a "change".
What are phosphorus's common isotopes?
Phosphorus is considered practically monoisotopic: P-31; radioactive isotopes P-32 and P-33 exist only in traces.
What is the relationship between atoms ad isotopes?
A natural chemical element may be monoisotopic or has isotopes. Isotopes are atoms but they differ from other isotopes by the number of neutrons. This involve a different atomic mass and different physical properties or sometimes (for light isotopes) different chemical properties. Also, all chemical elements have radioactive, artificial isotopes.
What are the natural abundance in percent of sodium's 3 most common isotopes?
Sodium is considered a monoisotopic chemical element - sodium-23; the isotopes sodium-22 and sodium-24 exist only in ultrtraces.
How tellurium and iodine show the periodic table is not arranged on basic of increasing atomic mass?
They show that the periodic table isn't arranged on the basis of increasing atomic mass because iodine has a mass lesser than tellurium. Iodine has a mass of 126.90 and tellurium has a mass of 127.60.
Do elements easily change into new elements?
No. It is quite difficult for elements to change into new elements.
Are there more elements or non-elements?
Non-elements. There are only around 118 known elements, there are millions of compounds made of those elements.
What are some Elements with hydrogen and oxygen?
Hydrogen and oxygen are already elements. Elements do not contain other elements.
What are the names of all the man made elements on the periodic table?
Transuranium Elements
What is the average sum of the elements divided by number of elements?
the sum of the elements divided by the number of elements is the average
