Front

What is a Lewis dot diagram?

Back

A Lewis dot diagram is a representation of the valence electrons of an atom, showing how they are arranged around the nucleus and how they bond with other atoms.

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

Back

The number of valence electrons can be determined by the group number of the element in the periodic table. For example, elements in Group 1 have 1 valence electron, while those in Group 2 have 2.

Front

What is covalent bonding?

Back

Covalent bonding is a type of chemical bond where two atoms share one or more pairs of electrons to achieve a full outer shell of electrons.

Front

What is the difference between a molecular formula and an empirical formula?

Back

A molecular formula shows the actual number of atoms of each element in a molecule, while an empirical formula shows the simplest whole-number ratio of the elements.

Front

What is the correct name for the compound CCl₄?

Back

The correct name for CCl₄ is carbon tetrachloride.

Front

What is the significance of prefixes in naming covalent compounds?

Back

Prefixes indicate the number of atoms of each element in a covalent compound. For example, 'di-' means two, 'tri-' means three, and 'tetra-' means four.

Front

How do you write the formula for a covalent compound?

Back

To write the formula for a covalent compound, use the symbols of the elements involved and the appropriate prefixes to indicate the number of each type of atom.

Front

What is the name of the compound N₂O₃?

Back

The name of the compound N₂O₃ is dinitrogen trioxide.

Front

What is the Lewis structure for Al?

Back

The Lewis structure for aluminum (Al) shows three dots around the symbol, representing its three valence electrons.

Front

What is the correct name for C₄H₆?
