Study Notes
The B series elements
- The 'B series' in the periodic table is a convention used to designate elements in the transition metal groups.
- These elements are located in groups 3 to 12 on the periodic table, sometimes referred to as "B groups" or "transition metals".
- The B series elements are known for their variable oxidation states, which means they can form ions with different charges.
Halogen Group
- The halogens are a group of non-metallic elements in Group 17 of the periodic table.
- They have 7 electrons in their outer shell, making them highly reactive and prone to form salts.
- Examples of halogens include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Lanthanide Series
- The lanthanides are a series of 15 metallic elements located in the f-block of the periodic table.
- They are also known as the rare-earth elements and are characterized by their similar chemical properties.
- Lanthanides are known for their use in various applications, including lasers, magnets, and electronics.
Alkali Metals
- Alkali metals are a group of highly reactive metallic elements in Group 1 of the periodic table.
- They have one electron in their outer shell, making them readily willing to lose an electron to form positive ions.
- Examples of alkali metals include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Periodic Table Rows
- Each horizontal row in the periodic table is called a period.
- Elements within the same period share the maximum number of electron shells, implying that they have similar atomic and chemical properties.
- The number of periods on the periodic table corresponds to the number of electron shells an atom has.
