In this manner, what is periodic table of elements?
The periodic table of elements arranges all ofthe known chemical elements in an informative array.Elements are arranged from left to right and top to bottomin order of increasing atomic number. Order generally coincideswith increasing atomic mass. The rows are calledperiods.
Also, what are the 118 elements and their symbols? Elements with their Symbol and Atomic Number in alphabeticalorder
| Symbol | Element | Atomic Number |
|---|---|---|
| Bi | Bismuth | 7 |
| Bh | Bohrium | 102 |
