1.2 - Ionic Bonding

What is an ion?

an atom that has lost or gained electrons to become postively or negatively charged

How is a positive ion formed?

when a metal atom loses electrons

Why does losing an electron form a positive ion?

because electrons have a negative charge, so when they get taken away, they are left with a more positive charge

How is a negative ion formed?

when a non metal atom gains electrons

Why does gaining an electron form a negative ion?

because electrons have a negative charge, so when they get gained, they are left with a more negative charge

Why do atoms bond?

to gain a full outer shell of electrons

Why do atoms want to gain a full outer shell of electrons?

for stability

What is ionic bonding?

when electrons are transferred from one atom to another

What substances does ionic bonding take place with?

metal and non metals

How does ionic bonding work?

a metal atom donates an electron to a non metal atom, so that they can both have a (stable) full outer shell

What is electrostatic attraction?

the positive and negative ions are strongly attracted to each other

What is an ionic bond?

an eectrostatic force of attraction between oppositely charged ions
