What is bond energy?

Back

Bond energy is the amount of energy required to break one mole of a bond in a molecule, measured in kilojoules per mole (kJ/mol).

Front

Which type of bond has the highest bond energy?

Back

Triple bonds have the highest bond energy compared to single and double bonds.

Front

What is the correct Lewis structure for BF3?

Back

The correct Lewis structure for BF3 has boron in the center with three fluorine atoms bonded to it, and no lone pairs on boron.

Front

What are the basic particles that make up ice crystals?

Back

Ice crystals are made up of molecules, specifically water molecules (H2O).

Front

What does the periodic table categorize?

Back

The periodic table categorizes elements into metals, metalloids, and non-metals.

Front

What is a dot diagram?

Back

A dot diagram, or Lewis dot structure, represents the valence electrons of an atom as dots around the element's symbol.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are anions and cations?

Back

Anions are negatively charged ions, while cations are positively charged ions.

Front

What is the difference between a single bond, double bond, and triple bond?

Back

A single bond involves one pair of shared electrons, a double bond involves two pairs, and a triple bond involves three pairs.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined from the group number of the element in the periodic table.
