Periodic Table: Periods and Groups
Introduction:
The periodic table is a tabular arrangement of all the chemical elements according to their atomic number, electron configuration, and chemical properties. The elements in the periodic table are arranged in horizontal rows and vertical columns.
Periods:
The horizontal rows in the periodic table are called periods. There are seven periods in the modern periodic table, and they are numbered from 1 to 7. Each period starts with an alkali metal and ends with a noble gas. The number of elements in each period increases as we move from left to right.
Groups:
The vertical columns in the periodic table are called groups. There are 18 groups in the modern periodic table, and they are numbered from 1 to 18. Elements in the same group have similar chemical properties and valence electron configurations. The elements in group 1 are called alkali metals, and the elements in group 18 are called noble gases.
Relationship between Groups and Periods:
The elements in the same period have the same number of electron shells, while the elements in the same group have the same number of valence electrons. The valence electrons are the electrons in the outermost shell of an atom. The properties of an element are determined by its valence electrons.
Conclusion:
In summary, the horizontal rows in the periodic table are called periods, and the vertical columns are called groups. The elements in the same period have the same number of electron shells, while the elements in the same group have the same number of valence electrons. Understanding the relationship between periods and groups is essential in predicting the chemical properties of elements.
