112 elements have been named and six more predicted.
The chemical formula for ammonium nitrate is NH4NO3. It consists of 3 elements: nitrogen, hydrogen and oxygen.
There are two elements in CO2, carbon and oxygen.
One common element is carbon. Anything that comes from the byproduct of a living thing contains carbon.
Elements 1 and 3 are hydrogen and oxygen, respectively. When combined, they form water, which is the most common substance in the body.
Zero. Elemnts always have a zero oxidation state hoever they are bonded. Helium is a noble gas, monoatomic and forms no compounds so as it happens it is always zero.

...as a solid.
The columns organise the elemnts according to the number of valence electrons that give rise to many of the similarities between the chemistry of the elemnts in the column. The rows organise in increasing atomic number.
NH4 contains two different elements. They are nitrogen (N) and hydrogen (H).
Out of the 100 elements in existence, only water and oxygen are necessary for survival.
Noble gases
He helped with the periodic table of elemnts.
Carbon dioxide contain carbon and oxygen.
science happens
The elements in a molecule of nitrous oxide are nitrogenand oxygen.
Yes,elements and compounds are pure substance.
His big task was to identify a pattern in the elemnts.
