Ionic Bonding

Flashcards about Ionic Bonding

Why are noble gases unreactive?

Atoms of noble gases have completely filled outer shells, making them stable and unreactive.

Why do atoms form bonds?

Atoms form bonds to achieve a full outer electron shell and become stable.

What is an ion?

An ion is an atom or group of atoms with an electrical charge due to gaining or losing electrons.

How do atoms form positive ions?

Atoms with nearly empty outer shells tend to lose electrons to form positive ions.

How do atoms form negative ions?

Atoms with nearly full outer shells tend to gain electrons to form negative ions.

How are ionic compounds formed?

Ionic compounds are formed by the reaction between a metal and a non-metal, involving the transfer of electrons.

What is an ionic bond?

Ionic bond is the strong electrostatic attraction between oppositely charged ions.

How do we represent the formation of an ionic compounds?

Dot-and-cross diagrams are used to represent the formation of ionic compounds, showing the transfer of electrons.

What is the relationship between electron loss and gain in ionic compounds?

In ionic compounds, the metal needs to lose the same number of electrons that the non-metal needs to gain.

What does the formula of a compound represent?

The formula of a compound shows the ratio of atoms of each element present using chemical symbols and numbers.

What is the process for determining the formula of an ionic compound?

Write down the symbol for each element, calculate the charge for each type of ion, balance the number of ions so that the positive and negative charges are balanced and equal zero and. use the ratio to write down the formula of the ionic compound.

What is an ionic lattice?

The ionic lattice is a giant 3D structure that continues to build until there are no more ions left to add.

Why do ionic compounds form crystals?

Ionic compounds form crystals due to the structure of the ionic lattice.

Why do ionic compounds have high melting and boiling points?

Ionic compounds have high melting and boiling points because ionic bonds are strong and require a lot of heat to break.

How can ionic compounds conduct electricity?

In liquid (molten) state, ions can break free and move, allowing ionic compounds to conduct electricity.

Why are ionic compounds brittle?

Ionic compounds are brittle because when hit, ions of like charge align, leading to repulsion and shattering.

What is an ionic lattice?

The giant 3D structure of an ionic compound.

How does the size of ionic charges affect the strength of bonds and melting point?

Larger ionic charges create stronger bonds and a higher melting point.
