Final answer:
The periodic table organizes elements based on their properties, such as atomic number, symbol, average atomic mass, and name. Elements with similar properties are grouped together in the same column. The table also has rows, called periods, which represent different levels of electron energy.
Step-by-step explanation:
The periodic table organizes elements based on their properties. Scientists use various properties to organize the periodic table, such as atomic number, symbol, average atomic mass, and name. Elements with similar properties are grouped together in the same column, known as a group. The table also has rows, called periods, which represent different levels of electron energy.
