Atomic symbols are used to represent elements, a negative (-) and a psoitive (+) represent electrons and protons, respectively. Chemicals or other compounds are often written as a combination of atomic symbols with subscripts to indicate the presence of multiple atoms.
A periodic chemistry is a periodic table. A periodic table is a tab,e with atoms and elements. Whatever we eat or use have atoms or elements.
As a chemist, Jöns Jacob Berzelius revolutionized the field by developing the modern system of chemical symbols and formulas, including introducing the use of letters to represent elements in formulas. He also determined accurate atomic weights for many elements and discovered several new elements such as cerium and selenium. Berzelius also made significant contributions to organic chemistry through his work on isomerism and catalysis.
How are elements and atoms related? An element is a substance that contains only a single type of atom. The number of atoms is not important as long as all the atoms are of the same type. You cannot separate an element into other substances..... there are as many elements as atoms - more them 100.
they both use hydrogen and oxygen. atoms make elements They both refer to the same thing. An atom is the smallest entity that makes up an element.
Molocules do not make new elements. Elements only change during atomic reactions, primarily nuclear fusion in stars. The atoms in a molecule are always the same, during chemical reactions they are only being rearranged. The oxygen you breathe in and the carbon dioxide that you breathe out, for example, are made of the same oxygen atoms.
Chemists organize information about atoms.
They use a structural formula.

They use the periodic table of elements. They all have their own abbreviations.
Chemist do not have gills
Examples: tongs, crucibles, laboratory stand, burettes, pipettes, balance, oven, Erlenmeyer flask etc.
The periodic table is full of elements.
