Lewis Dot Structures, Covalent and Ionic

Front

What are Lewis Dot Structures?

Back

Lewis Dot Structures are diagrams that represent the valence electrons of an atom. They show how electrons are arranged around the nucleus and how they bond with other atoms.

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 to achieve stability.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, typically between a metal and a non-metal.

Front

Where are the metalloids located on the periodic table?

Back

Metalloids are located along the zig-zag line that divides metals and non-metals on the periodic table.

Front

Why do elements bond?

Back

Elements bond to achieve a more stable electron configuration, often resembling that of noble gases.

Front

What is a lone pair of electrons?

Back

A lone pair is a pair of non-bonding electrons that are localized on a single atom.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable configuration.

Front

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

Back

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

Front

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond occurs when electrons are shared unequally between atoms, while a nonpolar covalent bond occurs when electrons are shared equally.
