Ionic Bonding Flashcards

All 7 cards in this deck

Which particles are the bonding particles in ionic bonding?

Oppositely charged ions.

What happens to electrons when a metal atom reacts with a non-metal atom?

Electrons in the outer shell of the metal atom are transferred to the non-metal atom.
The metal atom becomes a positive ion; the non-metal atom becomes a negative ion.

What is the charge on the ions formed by metals in Group 1 and in Group 2?

Group 1: $1+$; Group 2: $2+$.
e.g. $\mathrm{Na^+}$ and $\mathrm{Mg^{2+}}$

What is the charge on the ions formed by non-metals in Group 6 and in Group 7?

Group 6: $2-$; Group 7: $1-$.
e.g. $\mathrm{O^{2-}}$ and $\mathrm{Cl^-}$

What electronic structure do the ions of Group 1, 2, 6 and 7 elements have?

The electronic structure of a noble gas (Group 0) — a full outer shell.

What are the steps to draw a dot and cross diagram for the formation of an ionic compound?

e.g. sodium reacting with chlorine

1. Draw the outer shell electrons of each atom: Na has 1, Cl has 7.
2. Transfer the electron(s) from the metal to the non-metal so both have full outer shells.
3. Draw each ion in square brackets with its charge: $[\mathrm{Na}]^+$ and $[\mathrm{Cl}]^-$.

True or false? When an ionic compound forms, the non-metal atoms lose electrons.

False. Non-metal atoms gain electrons to become negatively charged ions; the metal atoms lose electrons.
