검증된 단계별 안내1
Understand that each element on the periodic table is represented by a unique one- or two-letter symbol derived from its English or Latin name.
Recall that potassium is a chemical element with the atomic number 19 and its symbol is derived from its Latin name 'Kalium'.
Recognize that the symbol for potassium is 'K', not 'P', 'Po', or 'Pt'.
Note that 'P' stands for phosphorus, 'Po' stands for polonium, and 'Pt' stands for platinum, which are different elements.
Therefore, the correct symbol representing potassium on the periodic table is 'K'.
