Ionic and Covalent Bonds

Front

What are valence electrons?

Back

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

Front

Where are valence electrons found?

Back

In the outermost energy levels of an atom.

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 between a metal and a non-metal.

Front

Which compound is an example of an ionic bond?

Back

CaCl2 (Calcium Chloride) is an example of an ionic bond.

Front

How many valence electrons does Strontium have?

Back

Strontium has 2 valence electrons.

Front

Why do atoms form bonds?

Back

Atoms form bonds to fill their outermost energy level, achieving stability.

Front

What do atoms that form positive ions tend to do?

Back

Atoms that form positive ions tend to lose electrons.

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

Give an example of a covalent compound.

Back

H3N (Ammonia) is an example of a covalent compound.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between charged ions, while covalent bonds involve the sharing of electrons between atoms.
