Ionic and Covalent Bonds

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, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

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

What is the charge of an oxygen atom with 8 protons and 10 electrons?

Back

O^2-

Front

Why are atoms most stable when their outer shell is complete?

Back

Atoms are most stable when their outer shell is complete because this configuration minimizes energy and maximizes stability.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that represents the valence electrons of atoms within a molecule, showing how they are arranged and bonded.

Front

How are ionic bonds formed?

Back

Ionic bonds are formed by the transfer of electrons from one atom to another, leading to the attraction between positively and negatively charged ions.

Front

What is the chemical formula for the ionic bond between Aluminum and Oxygen?

Back

The chemical formula is Al³⁺O^2-.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are crucial in determining how an atom will bond with others.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
