Ionic & 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 attraction between positively and negatively charged ions.

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

How many electrons can the first electron shell hold?

Back

The first electron shell can hold a maximum of 2 electrons.

Front

How many electrons can the second electron shell hold?

Back

The second electron shell can hold a maximum of 8 electrons.

Front

What are valence electrons?

Back

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

Front

How many valence electrons does an atom with 5 valence electrons have?

Back

An atom with 5 valence electrons has 5 electrons in its outermost shell.

Front

What happens to electrons in an ionic bond?

Back

In an ionic bond, electrons are transferred from one atom to another.

Front

What happens to electrons in a covalent bond?

Back

In a covalent bond, electrons are shared between two atoms.

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 the difference between ionic and covalent bonds?

Back

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