Naming Ionic vs Covalent compounds
How do you name an ionic compound that contains a multivalent metal?
To name an ionic compound with a multivalent metal, include the metal's charge in Roman numerals.
What does it mean to balance a chemical equation?
Balancing a chemical equation means making sure the number of atoms of each element is the same on both sides of the equation.
What is the suffix added to the name of a non-metal in an ionic compound?
The suffix "-ide" is added to the name of a non-metal in an ionic compound.
For example, chlorine becomes chloride in NaCl (sodium chloride).
What law must be followed when balancing a chemical equation? and why?
The Law of Conservation of Mass must be followed when balancing a chemical equation because it states that the total mass of reactants must equal the total mass of products, meaning atoms cannot be created or destroyed during a chemical reaction.
How do you name a covalent compound with two non-metals?
To name a covalent compound with two non-metals, use prefixes to indicate the number of atoms and add "-ide" to the second element
When balancing a chemical reaction, what do you adjust to make the number of atoms equal on both sides?
When balancing a chemical reaction, you adjust the coefficients in front of the chemical formulas to make the number of atoms equal on both sides.
What is the key difference between ionic and covalent compounds in terms of how they bond?
The key difference is that ionic compounds form when atoms transfer electrons (metal + non-metal), while covalent compounds form when atoms share electrons (non-metal + non-metal).
Which elements should you balance last in a chemical equation? Why?
You should balance oxygen and hydrogen last in a chemical equation because they are often found in multiple compounds and adjusting them first can make it harder to balance other elements.
How do you identify a polyatomic ion in an ionic compound?
A polyatomic ion in an ionic compound can be identified by looking for a group of atoms that have a charge.
In a balanced chemical equation, how do the number of atoms of each element compare on both sides?
In a balanced chemical equation, the number of atoms of each element is the same on both sides.
