Pure substances made from only one type of atom are?
This would be called an element, or a mono-atomic compound.
What are the elements in Phenol?
There are three elements. They are carbon,hydrogen and oxygen.
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 some Elements with hydrogen and oxygen?
Hydrogen and oxygen are already elements. Elements do not contain other elements.
How many elements were there in 1860?
63 elements had been discovered so far.
How many elements in the periodic table are monoisotopic?

What is the percent composition of beryllium?
Beryllium is a monoisotopic chemical element.
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.
Is an element a physical or chemical change is it homogeneous or heterogeneous?
An element is a pure substance that is the simplest form of matter and cannot be broken down into simpler substances by chemical means. Therefore, an element is not considered to undergo a physical or chemical change. Additionally, elements are considered homogeneous because they consist of only one type of atom throughout.
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.
How many elements are found in the periodic table of elements?
There are a total of 118 elements known to exist on the periodic table.
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
What elements have more predictable properties main group elements or transition elements?
main group elements
What are the names of all the man made elements on the periodic table?
Transuranium Elements
