Q. What holds the ions together in an ionic bond?
Ionic bonding An ionic lattice is held together by strong electrostatic forces of attraction between the oppositely charged ions. The forces act in all directions in the lattice. This is called ionic bonding .
Q. What holds together positive and negative ions?
An ionic bond is the force of attraction that holds together positive and negative ions. It forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. Ionic bonds form only between metals and nonmetals.

Q. Why do ions come together?
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.
Q. Do ions exist by themselves?
Ions of like charge repel each other, and ions of opposite charge attract each other. Therefore, ions do not usually exist on their own, but will bind with ions of opposite charge to form a crystal lattice. The resulting compound is called an ionic compound, and is said to be held together by ionic bonding.
Q. What is the chemical name for the formula Na2S?
Sodium sulfide
Q. Is Na2S acid or base?
Sodium sulfide (Na2S) is an strong alkaline solution and is acidic in nature.
Q. Why is li2o less soluble in water?
The Lithium oxide and magnesium oxide have high lattice enthalpy than hydration enthalpy. Hence , both are less soluble in water.
Q. Is PCl5 ionic?
Why is PCl5 solid? So it exists as an ionic compound with formula [PCl4]+[PCl6]-. It’s solid because it’s ionic make strong bond and intermolecular interactions is more.
Q. Why AlCl3 is covalent but NaCl is ionic?
NaCl is more ionic compared to the ionic nature of AlCl3. In NaCl both cation and anion have low charges while in AlCl3 the cation Al3+, is of a higher charge than Na+ while the anion is the same in both compounds. According to the Fajan’s rule, AlCl3 is more covalent in nature.
Q. Is LICL ionic?
Lithium chloride is an ionic compound but it also has some covalent character due to the very small size of lithium metal.
Q. Why is Al2O3 ionic?
Al2O3 is ionic due to relative size of oxygen and aluminium and polarizing power of Al, (since we know that aluminium has a charge of +3, provides three electrons) in case of Al2Cl6 & AlCl3 , it seems to be covalent due to similarities like banana bonding & bigger radius of Cl (in compression to oxygen).
