Formation of Ionic Compounds

If my charge becomes 2+ what does that say about me?

• I am stealing 2 electrons
• I am losing 2 electrons
• I am in period 2
• I have an atomic # of 2

If I gain electrons I become

• Positive because I've added to my atom
• negative because I've added electrons
• same because i'm balanced
• equal because now I have electrons

The first step in naming an ionic compound is always...

• Naming the anion (non-metal)

• Changing the ending to -ide

• Naming the cation (metal)

• Writing the cation charge

Magnesium bromide is an ionic compound with the chemical formula MgBr₂.  What does the "2" tell you?

• There are 2 bromide ions for every magnesium ion
• Bromide has a 2- charge
• Bromide has a 2+ charge
• There are 2 magnesium ions to every bromide ion

For an ionic compound formula, write:

(pick the two correct answers)

• Metal first

• Non-Metal first

• Cation first

• Anion first

When naming a compound, what must the last part be?

• the element with "ide" at the end

  (ALWAYS!)

• the element with the ending "ite"

• the name of the element

• the element with "ide" at the end
  (unless its a polyatomic ion!)

What is the overall charge of the ionic compound NaCl

• +1

• +2

• +3

• 0
