Ionic Bonds and Dot and Cross Diagrams

What are ions?

• Particles that bond together through ionic bonds

• Atoms that lose or gain electrons

• Atoms with full outer shells

• Particles with opposite charges

How can ions be represented using equations?

• By showing the movement of electrons with arrows

• By placing big square brackets around them

• By writing the atom's charge in the top right corner

• By drawing dots and crosses to represent electrons

What is the force that holds ions together in an ionic compound?

• Covalent bond

• Ionic bond

• Electrostatic force

• Metallic bond

What type of bond is an ionic bond?

• Weak

• Moderate

• Strong

• Unstable

How are electrons represented in a dot and cross diagram?

• As dots

• As crosses

• As arrows

• As shells

What is the general rule for the movement of electrons in an ionic bond?

• Electrons move from the non-metal to the metal

• Electrons move from the metal to the non-metal

• Electrons move from the outermost shell to the inner shells

• Electrons move randomly between atoms
