Lithium (Li) and Magnesium (Mg)
What is a characteristic of the diagonal relationship between Lithium (Li) and Magnesium (Mg)?
Similar electronegativities and covalent character
What property is exhibited by Beryllium (Be) and Aluminum (Al) as part of their diagonal relationship?
Formation of amphoteric oxides and hydroxides
What is a characteristic of Boron (B) and Silicon (Si) as part of their diagonal relationship?
Formation of covalent compounds and existence as semiconductors
Why is the diagonal relationship more noticeable amongst the lighter elements?
Due to their similar properties and smaller atomic sizes
Which statement is true about the diagonal relationship between the elements in the periodic table?
It is less noticeable after boron and silicon
What is a common characteristic of the elements involved in the diagonal relationship?
Similar atomic radii and covalent character
What is the trend for metallic character moving across a period and down a group?
Decreases across a period, increases down a group
What is the relationship between boiling points and the periodic table trends?
Boiling points increase across metals from left to right within a period and decrease sharply when moving from metals to nonmetals on the right
What is the reason for the diagonal relationship between boron and silicon with their diagonally adjacent element pairs?
Due to equal polarizing power, ionic potential, and variation of atomic properties across the periodic table

Can form triple bonds, strong pi and sigma bonds, exhibit allotropes, and have similar electronegativities
What is the trend for metallic character across a period?
Decreases across a period

Both exhibit diamagnetism
What is the trend for boiling points across a period?
Varies on the periodic table in a regular pattern
Study Notes
Periodic Table Trends, Diagonal Relationships, and Metallic Character
- Boron and silicon share similarities with their diagonally adjacent element pairs
- Carbon and Phosphorus can form triple bonds, strong pi and sigma bonds, exhibit allotropes, and have similar electronegativities
- Nitrogen and Sulfur both exhibit diamagnetism
- Diagonal relationship is due to equal polarizing power ionic potential and variation of atomic properties across the periodic table
- Trend moving down the periodic table tends to be opposite of the trend moving across
- Metallic character decreases across a period and increases down a group
- Metals lose electrons easily and are good conductors of electricity and heat
- Nonmetals have a strong pull or attraction to their electrons and are poor conductors
- Metallic character trend follows the atomic radii trend
- Boiling point trend varies on the periodic table in a regular pattern
- Boiling points increase across metals from left to right within a period
- Boiling points decrease sharply when moving from metals to nonmetals on the right
