Explain the difference between ionic and covalent compounds.
Ionic compounds are between a metal and non-metals. A covalent compound are a metalloid and metal or 2 non-metals
Which type of elements form covalent compounds?
Nonmetals and metalloids
Ahh C.J. type of elements form ionic compounds?
Metals + nonmetals, polyatomic
What is an ion?
An atom with a positive or negative charge
How are ions formed?
Loss or gain of electrons
What are cations? Which elements form cations?
Less electrons (positive) + charge metals are cations
What are anions? Which elements form anions?
Have more electrons (-) charge. Any nonmetal
Know which group of elements form which ions. For example, Group IA elements form what charge?
VA (-3) V/A( VIIA
Compounds formed with polyatomic ions are covalent or ionic?
Ionic
Where are transition metals located on the periodic table?
In the middle of the periodic table
Do transition metals form cations or anions?
Cations
What is the significance of a Roman numeral in a compound name? For who do elements must a Roman numeral be included?
Shows charge of transition metals
Can the formula for magnesium hydroxide be written MgOHv2?
No, (OHv2) needs ( ).
What is the special rule for Hydrogen when determining if the compound is ionic or covalent?
When (H) is in the front of 2 compound is considered a metal so it’s ionic. If it’s in the back it’s covalent
What is always written/named first?
Cation (positive)
