ionic and covalent bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically formed when one atom donates an electron to another.

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

Why do atoms form bonds?

Back

Atoms form bonds to achieve a full outermost energy level, which makes them more stable.

Front

What are valence electrons?

Back

Valence electrons are the electrons located in the outermost energy level of an atom that are involved in forming bonds.

Front

How do you determine the formula for an ionic compound?

Back

To determine the formula for an ionic compound, combine the symbols of the ions and balance the total positive and negative charges.

Front

What is the significance of 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 stability.

Front

What is the formula for sodium chloride?

Back

The formula for sodium chloride is NaCl.

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 a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be either covalent or ionic.

What is the name of the compound with the formula CO₂?

Back

The name of the compound CO₂ is carbon dioxide.
