Groups 1A through 3A follow what rules when forming ions?
|
Groups 1A through 3A form cations with positive charges equal to their group number.
|
|
|
What are monatomic ions?
|
Monatomic ions are ions consisting of a single atom with a positive or negative charge according to how many electrons the ion has lost or gained.
|
|
|
Why are transition metal ions different than ions formed from groups 1A, 2A, and 3A?
|
Transition metal atoms can form cations with different charges, while atoms from groups 1A, 2A, and 3A can only form one type of cation.
|
|
|
How can you determine the charge of a Group A nonmetal ion?
|
Subtract 8 from the group number. (Note: This only works when you use the A/B number designations, which are 4A through 7A.)
|
|
|
What are polyatomic ions?
|
Polyatomic ions are a group of covalently bonded atoms which act in a unit and carry a charge.
|
