What type of ions are held together by electrostatic attraction?
Positive and negative ions
Under what conditions can ionic compounds conduct electricity?
When molten or dissolved in solution.
What is the title of the image?
Ionic Bonding in Sodium Chloride
How does a non-metal become a negative ion?
By receiving electrons and gaining a negative charge.
Why are ionic compounds considered brittle?
Same-charge ions repel when aligned.
What is a key property of ionic compounds regarding melting points?
They have high melting points.
What analogy is used to describe the attraction between oppositely charged ions?
Like magnets with north and south poles
What happens to sodium (Na) in the formation of sodium chloride (NaCl)?
Sodium loses an electron to chlorine.
How do positive ions like Na⁺ interact with negative ions like Cl⁻?
They are held together by electrostatic attraction
Why do ionic compounds have high melting points?
Strong electrostatic forces hold ions together.
What ion does chlorine (Cl) become after gaining one electron?
Cl⁻
How does ionic bonding occur between a metal and a non-metal?
A metal gives electrons to a non-metal.
What is the role of electrostatic attraction in ionic bonding?
It holds oppositely charged ions together
What is the chemical formula of the chloride ion?
Cl-
What is the chemical formula of the sodium ion? 
Na+
What types of ions are formed in ionic bonding?
Positive and negative ions are formed.
What role does chlorine (Cl) play in the formation of sodium chloride (NaCl)?
Chlorine gains an electron from sodium.
What is the metal in Calcium Oxide (CaO)?
Calcium (Ca)
What is the non-metal group in Magnesium Sulfate (MgSO4)?
Sulfate (SO4)
What is the chemical formula for table salt?
The formula is NaCl.
What is the non-metal in Calcium Oxide (CaO)?
Oxygen (O)
What is the non-metal in Potassium Iodide (KI)?
Iodine (I)
What happens to ionic compounds when stress is applied?
The ion layers shift, causing breakage.
What is the metal in Sodium Chloride (NaCl)? 
Sodium (Na)
What does the arrow in the diagram indicate about the Na⁺ ion?
It is attracted to the Cl⁻ ion
What is the relationship between metals and non-metals in ion formation?
Metals lose electrons; non-metals gain electrons.
What is Magnesium Sulfate (MgSO4) commonly found in?
Epsom salts
What do all the listed ionic compounds demonstrate about ionic bonding?
Formation of ions
Strong electrostatic attraction
Defined by ionic bonding characteristics
What is the metal in Potassium Iodide (KI)? 
Potassium (K)
What ion does sodium (Na) become after losing one electron?
Na⁺
What happens when a metal gives away electrons?
It becomes a positive ion.
What is the metal in Magnesium Sulfate (MgSO4)? 
Magnesium (Mg)
What is Calcium Oxide (CaO) used for?
Used in cement
Why do positive and negative ions stick together in ionic bonding?
They stick together due to opposite charges.
How do the sodium ion and chloride ion form an ionic bond?
The sodium ion (Na+) has a positive charge
The chloride ion (Cl-) has a negative charge
The opposite charges attract, forming an ionic bond
This results in the stable compound sodium chloride (NaCl)
How can the ionic bonding in sodium chloride be represented visually?
The sodium ion (Na+) is represented by a blue circle
The chloride ion (Cl-) is represented by a purple circle
The ionic bonds between them are shown by the blue arrows
How do ionic compounds conduct electricity in liquid or solution states?
Mobile ions carry electric charge.
How can the formation of positive and negative ions be explained using a toy analogy?
Metals "give" electrons like sharing toys.
Non-metals "receive" electrons, gaining a negative charge.
Metals become positive ions, non-metals become negative ions.
What is the non-metal in Sodium Chloride (NaCl)?
Chlorine (Cl)
What is Potassium Iodide (KI) used in?
Used in iodized salt
