Ionic bonding

Front

What is ionic bonding?

Back

Ionic bonding is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of charged ions that attract each other.

What happens to valence electrons in ionic bonding?

Back

In ionic bonding, there is a transfer of valence electrons from one atom (usually a metal) to another atom (usually a non-metal).

What is the charge of a sodium ion (Na⁺)?

Back

The charge of a sodium ion (Na⁺) is +1, indicating it has lost one electron.

Front

What is the charge of a chloride ion (Cl^-)?

Back

The charge of a chloride ion (Cl^-) is -1, indicating it has gained one electron.

What is the chemical formula for the compound formed between sodium and chlorine?

Back

The chemical formula for the compound formed between sodium and chlorine is NaCl.

Front

What is the name of the compound NaCl?

Back

The name of the compound NaCl is Sodium Chloride.

Front

How many electrons are needed in the outer energy levels of an atom to be stable?

Back

An atom needs 8 electrons in its outer energy level to be stable, following the octet rule.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is a noble gas and its charge?

Back

A noble gas is an element in group 18 of the periodic table that has a full outer shell of electrons, resulting in a charge of 0 because they do not exchange electrons.

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.
