A time interval in which a particular phenomenon or motion is observed to repeat regularly at roughly equal intervals.
A concept in which similar events or phenomena occur consistently over approximately the same duration, indicating a rhythmic or systematic pattern.
In the context of chemistry, it refers to a horizontal grouping of elements in the periodic table that exhibit similar properties, highlighting a periodic relationship among them.
A complete cycle of motion or change in a system, particularly in relation to astronomical phenomena.
The time taken for a celestial body to return to its original position, often used in discussions of orbits and rotations in astronomy.
A designated interval in which repetitive events occur, marking the beginning and end of a recurring process in the context of astronomical activities.
Describing a phenomenon that occurs repeatedly at regular intervals, suggesting a consistent and predictable pattern over time.
Characterizing events or changes that happen in a systematic manner, often resulting in similar outcomes at equal time intervals.
Indicating the recurrence of similar situations or conditions at defined time frames, which may be observed in natural processes or sequences.
Example:
そ の火山は周期的に噴火を繰り返す。
A chart that organizes chemical elements based on their atomic number and recurring properties, illustrating the periodic law that led to the development of the arrangement of elements in rows and columns.
A systematic representation of elements where elements with similar chemical behaviors and properties are grouped together, helping to understand their relationships and predict future discoveries.
A structured table that reveals the periodic trends and relationships among different elements, serving as an essential tool for chemists and students to navigate the complexities of elemental interactions.
