Ionic Bonding Flashcards
How are ions formed
Atoms take part in chemical reactions to achieve an outer shell of electrons. They achieve this by losing or gaining electrons until they achieve that full outer shell.
What are the charges for group 1,2,3 metals?
Group 1= +1
Group 2= +2
Group 3= +3
What are the charges for group 5,6,7?
Group 5= -3
Group 6= -2
Group 7= -1
What is an ionic bond?
An ionic bond is the electrostatic force of attraction between the positive cation and negative anion.
What are the charges for iron (II) and (III)?
Iron II = +2
Iron III = +3
What is the charge of a zinc ion?
+2
What is the charge for lead?
+2
What is the charge for copper
+2
What is the charge for silver?
+1
What is the formula for a carbonate?
CO3 (-2 charge)
What is the formula for a nitrate?
NO3 (-1 charge)
What is the formula for ammonium?
NH4 (+1 charge)
What is the formula for a hydroxide?
OH (-1 charge)
What is the formula for sulfate?
SO4 (-2 charge)

Why do ionic compounds have high melting/boiling points
Because ionic compounds are a giant structure of ions and are held together by very strong ionic bonds. These bonds are very hard to overcome and require a lot of energy, causing them to have high melting and boiling points.
How do non metals and metals act to form an ionic compound?
When a non metal and a metal react to form a compound, a transfer of electrons from the metal to the non metal occurs.
Do metals lose or gain electrons?
Metal atoms lose electrons to form positively charged ions.
Do non metals lose/gain electrons?
Non metals gain electrons to form negatively charged ions, an anion
