What can you see in the periodic table?
Within each element square, information on the element’s symbol, atomic number, atomic mass, electronegativity, electron configuration, and valence numbers can be found.
How do we use the periodic table in everyday life?
Summary
- The table can be used to predict the properties of elements, even those that have not yet been discovered.
- Columns (groups) and rows (periods) indicate elements that share similar characteristics.
- The table makes trends in element properties apparent and easy to understand.
How do you read table elements?
Read the periodic table from top left to bottom right. The elements are ordered by their atomic numbers, which increase as you move across and down the periodic table. The atomic number is how many protons the element’s atom possesses.
