Physical Science Ionic & Covalent Bond Quest

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost orbital of an atom that are involved in forming bonds with other atoms.

Front

Where are valence electrons located in an atom?

Back

In the outermost orbital of an atom.

Front

Which atoms need 2 electrons to be stable?

Back

Oxygen and Sulfur need 2 electrons to be stable, while Lithium only needs 1.

Front

What type of bond forms between Hydrogen and Oxygen?

Back

A covalent bond.

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that involves the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is the difference between ionic and covalent bonds?

Back

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

Front

What is the chemical formula for three hydrogen, one sulfur, and four oxygen?

Back

H₃SO₄.

Front

What is the octet rule?

Back

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

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be either the same or different elements.
