What does the periodic law state?
The periodic law states that when you arrange elements by the order of increasing their atomic number, you will periodically see a repetition of their chemical and physical properties.
The periodic law states that when you arrange elements by the order of decreasing their atomic mass, you will periodically see a repetition of their chemical and physical properties.

The correct answer is:
The periodic law states that when you arrange elements by the order of increasing their atomic number, you will periodically see a repetition of their chemical and physical properties.
To understand this law, you can follow these steps:
1. Start by arranging the elements in the periodic table in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom.
2. As you arrange the elements, pay attention to their properties such as reactivity, atomic radius, ionization energy, and electronegativity.
3. Notice that elements within the same group or column tend to have similar chemical and physical properties. For example, elements in Group 1 (alkali metals) are all highly reactive and have low ionization energies.
4. Also observe that elements in the same period or row exhibit a gradual change in properties. For example, moving from left to right across a period, elements generally become less metallic and more nonmetallic.
5. These repeating patterns of properties are a result of the periodic law. The law states that the properties of elements are periodic, meaning they repeat at regular intervals, as you move across the periodic table.
By understanding and applying the periodic law, scientists have been able to organize and predict the behavior of elements, leading to advancements in various fields such as chemistry, materials science, and engineering.
