Ionic Bonding

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when one atom donates electrons to another, resulting in the formation of cations and anions.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed by the loss of one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed by the gain of one or more electrons.

How many valence electrons does Silicon (Si) have?

Back

Silicon has 4 valence electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full set of eight valence electrons, achieving stability.

Front

What is the formula for Sodium oxide?

Back

The formula for Sodium oxide is Na₂O.

Front

How many electrons does Silicon need to gain to become stable?

Back

Silicon needs to gain 4 electrons to achieve a stable octet.

Front

What is the charge of a magnesium ion (Mg²⁺)?

Back

The charge of a magnesium ion (Mg²⁺) is +2, indicating it has lost two electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the significance of the periodic table in determining valence electrons?

Back

The periodic table helps identify the number of valence electrons in an element based on its group number, which is crucial for predicting bonding behavior.
