ionic and covalent bonding

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that forms between positive ions and negative ions.

Front

How many electrons are needed to complete the first energy level?

Back

2 electrons are needed to complete the first energy level.

Front

How many electrons are needed to complete the second energy level?

Back

8 electrons are needed to complete the second energy level.

Front

What are valence electrons?

Back

Valence electrons are the outer shell electrons that are involved in forming bonds.

Front

What happens when a metal loses an electron?

Back

When a metal loses an electron, it becomes a positive ion.

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

What is a positive ion?

Back

A positive ion is an atom that has lost one or more electrons, resulting in a net positive charge.

Front

What is a negative ion?

Back

A negative ion is an atom that has gained one or more electrons, resulting in a net negative charge.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

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.
