Unit 3H Celebration - Covalent Compounds

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What are covalent compounds?

Back

Covalent compounds are substances formed when two or more nonmetals bond by sharing electrons.

Front

What is the general trend in atomic radius among halogens?

Back

The atomic radius decreases as you move from iodine (I) to fluorine (F) in the periodic table.

Front

Which element in group 7A has the smallest atomic radius?

Back

Fluorine (F) has the smallest atomic radius among the halogens.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

How do you represent a covalent bond in a Lewis dot structure?

Back

A covalent bond is represented by a line between two atoms, indicating shared electron pairs.

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds are typically formed between nonmetals.

Front

What is the significance of shared electrons in covalent bonding?

Back

Shared electrons allow atoms to achieve a full outer shell, leading to greater stability.

Front

What is a hydrocarbon?

Back

A hydrocarbon is a compound made up entirely of hydrogen and carbon atoms.

Front

Where do short chain hydrocarbons collect in a fractional distillation column?

Back

Short chain hydrocarbons collect at the top of the fractional distillation column.
