Use The Periodic Table To Fill In The Below Chart
Introduction
Learning chemistry can be a daunting task, especially when it comes to understanding the periodic table. However, the periodic table is an essential tool for understanding the properties of elements and their relationship to each other. In this article, we will explore how to use the periodic table to fill in a chart and better understand the properties of elements.
The Periodic Table
The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and chemical properties. It contains 118 elements arranged in order of increasing atomic number. The elements are arranged in groups and periods, which are based on the electron configurations of the elements.
The Chart
The chart we will be filling in is a table that lists the properties of elements based on their group and period. The chart has five columns, including the element symbol, atomic number, group, period, and a property of the element. The property of the element can be any physical or chemical property, such as melting point, boiling point, or electronegativity.
Filling in the Chart
To fill in the chart, we will need to understand the properties of elements based on their group and period. Elements in the same group have similar properties, while elements in the same period have the same number of electron shells. We can use this information to fill in the chart.
Group 1: Alkali Metals
The elements in group 1 of the periodic table are known as alkali metals. They are highly reactive and have a single valence electron. As we move down the group, the elements become more reactive and have lower melting and boiling points. The property we will list in the chart for group 1 is their reactivity with water. This property increases as we move down the group.
Group 2: Alkaline Earth Metals
The elements in group 2 of the periodic table are known as alkaline earth metals. They are also highly reactive but have two valence electrons. As we move down the group, the elements become more reactive and have lower melting and boiling points. The property we will list in the chart for group 2 is their reactivity with oxygen. This property also increases as we move down the group.
Group 17: Halogens
The elements in group 17 of the periodic table are known as halogens. They are highly reactive and have seven valence electrons. As we move down the group, the elements become less reactive and have higher melting and boiling points. The property we will list in the chart for group 17 is their reactivity with metals. This property decreases as we move down the group.
Group 18: Noble Gases
The elements in group 18 of the periodic table are known as noble gases. They are inert and have a full valence electron shell. They have very low reactivity and do not readily form compounds. The property we will list in the chart for group 18 is their boiling point. This property increases as we move down the group.
Conclusion
The periodic table is a powerful tool for understanding the properties of elements. By using the periodic table to fill in the chart, we can better understand the properties of elements based on their group and period. This knowledge can be useful in a variety of applications, including chemistry, materials science, and engineering.
