Periodic Table Flashcards
How is the Periodic Table arranged?
By increasing atomic number (protons)
The arrangement allows for the classification of elements based on their properties.
What are groups in the Periodic Table?
Columns that indicate similar properties
Elements in the same group often have similar chemical behaviors.
What are periods in the Periodic Table?
Rows that indicate the number of shells
The period number corresponds to the number of electron shells an atom has.
Where are metals located in the Periodic Table?
On the left side
Metals typically exhibit properties such as malleability and conductivity.
Where are non-metals located in the Periodic Table?
On the right side
Non-metals have varied properties and are generally poor conductors.
What is Group 1 in the Periodic Table?
Alkali Metals, which are highly reactive
Alkali metals react vigorously with water.
What do alkali metals form when they react with water?
Metal Hydroxide and Hydrogen Gas
This reaction can be explosive, especially with heavier alkali metals.
What is Group 7 in the Periodic Table?
Halogens, which have reactivity that decreases down the group
Halogens are known for forming diatomic molecules like Cl2 and Br2.
What do halogens form when they react with metals?
Salts
This is a common characteristic of halogen reactions with metals.
What is Group 0 in the Periodic Table?
Noble Gases, which are unreactive due to having a full outer shell
Noble gases are known for their lack of reactivity and are used in lighting and other applications.
