Why do atoms form ions?

• To reduce their atomic mass

• To increase their atomic number

• To become more reactive

• To achieve a full outer shell of electrons

How does a sodium atom achieve stability?

• By sharing its outermost electrons

• By gaining one electron

• By losing one electron

• By splitting into two atoms

Why are full outer shells considered stable in chemistry?

• They enhance reactivity

• They increase atomic size

• They fulfill the octet rule

What is the purpose of using square brackets in ionic compounds?

• To indicate the presence of water molecules

• To show the charge of the ions

• To represent covalent bonds

• To highlight the metal atoms

What is the significance of opposite charges in ionic bonding?

• They have no effect on bonding

• They attract, forming a strong bond

• They neutralize each other

• They repel, breaking the bond
