Naming chemicals
What is the prefix tri-?
Indicate three atoms of an element in covalent compounds.
What bond is created when combining a metal and a nonmetal?
Ionic bond
What is the name of MgO?
Magnesium oxide
What is the name of CO2?
Carbon dioxide
In metallic bonds, what allows metals to conduct electricity?
Electrons move freely and carry electric current.
What is the name for NaCl?
Sodium Chloride.
How does electron behavior in ionic bonds differ from covalent bonds?
In ionic bonding, electrons are transferred, while in covalent bonds electrons are shared.
What is the name of NaOH?
Sodium Hydroxide
What is the formula for dioxygen difluoride?
O2F2
Why do metals generally have high melting and boiling points?
Strong attractions between metal ions require a lot of energy to break.
Determine the name of P2O5.
Diphosphorus Pentoxide.
Why do ionic compounds have high melting and boiling points?
The strong attraction between oppositely charged ions requires a lot of energy to break.
What is the name of Ca3P2?
Calcium phosphide
What is the formula for Phosphorus Pentachloride?
PCI5
Why are metals malleable?
The sea of electrons allows metal ions to slide past each other without breaking bonds.
How are FeCl2 and FeCl3 different?
FeCl2 is Iron (II) Chloride, while FeCl3 is Iron (III) Chloride.
How does lattice energy relate to the strength of an ionic bond?
It is the energy needed to separate one mole of an ionic compound into its ions.
What is the name of Al2(CO3)3?
Aluminum Carbonate
What is the name for Cl5P?
Phosphorus Pentachloride
What happens to electrons in a metallic bond?
Electrons form a sea that surrounds the metal ions.
What is the formula of aluminum sulfate?
Al2(SO4)3
How does electron transfer lead to the formation of an ionic bond?
One atom transfers electrons to another, forming positive and negative ions that attract each other.
What is the name of Cu3(PO4)2?
Copper(III) Phosphate
What is the name of CCl4?
Carbon Tetrachloride
What is an alloy?
A mixture of two or more elements, at least one of which is a metal.
