Question

comparing ionic and covalent compounds
use the chart to help you compare ionic compounds and covalent compounds. on
the left side, place the letters of the statements that are only true of ionic compounds.
on the right side, place the letters of the statements that are only true of covalent
compounds. in the middle, place the letters of the statements that are true of both
compounds.
a. atoms gain or lose electrons to form ions
b. pure substance made up of two or more kinds of elements
c. compound is made of a positive ion and a negative ion
d. atoms join by sharing electrons
e. atoms are joined to each other by chemical bonds
f. exist as a solid in the form of an ionic lattice
g. oppositely charged ions attract each other
h. molecule made of uncharged atoms
i. bond between atoms is due to electron transfer
j. compound is made of a non - metal and a non - metal
k. sodium chloride (nacl) is an example
l water (h₂o) is an example

Explanation:

Ionic Compounds (Only True for Ionic):

• A: Ionic compounds form when atoms gain/lose electrons to form ions (electron transfer).
• C: Ionic compounds consist of positive (cation) and negative (anion) ions.
• F: Ionic compounds exist as a solid ionic lattice (e.g., NaCl crystals).
• G: Oppositely charged ions attract (ionic bonding is electrostatic attraction).
• I: Ionic bonds involve electron transfer (from metal to non - metal).
• K: NaCl is an ionic compound (metal + non - metal, forms ions).

Both Ionic and Covalent:

• B: Both are compounds (pure substances with two or more elements).
• E: Both have atoms joined by chemical bonds (ionic or covalent bonds).

Covalent Compounds (Only True for Covalent):

• D: Covalent compounds form when atoms share electrons (covalent bonding).
• H: Covalent compounds are molecules of uncharged atoms (no ions, just shared electrons).
• J: Covalent compounds are non - metal + non - metal (e.g., \(H_2O\), \(CO_2\)).
• L: \(H_2O\) is a covalent compound (non - metals sharing electrons).

Answer:

Ionic compound	Both	Covalent compound
