C2 - Ionic Bonding

Question 1

What is an ionic bond?

Answer 1

When a metal or nonmetal react together, the metal atom loses electrons to form a positively charged ion and a non-metal gains these electrons to form a negatively charged ion. These oppositely charged ions are strongly attracted to one another by electrostatic forces.

Question 2

What do dot and cross diagrams show?

Answer 2

Dot and cross diagrams show the arrangement of electrons in an atom or ion. Each electron is represented by a dot or a cross.So these diagrams can show which atom the electrons in an ion originally came from

Question 3
