What is an ionic bond?
A chemical bond formed through the transfer of electrons between a metal and a nonmetal.
What is a covalent bond?
A chemical bond formed by the sharing of electrons between two nonmetals.
What is metallic bonding?
A type of chemical bonding that occurs between metal atoms where electrons are shared in a sea of electrons.
Name the compound NaCl.
Sodium chloride
Which types of elements typically form ionic bonds?
Metals and nonmetals.
How are electrons shared in a covalent bond?
Electrons are shared equally or unequally between two atoms.
Describe the "sea of electrons" in metallic bonds.
The outer electrons are free to move throughout the metal, allowing for electrical conductivity and malleability.
What is the name for CO2?
Carbon dioxide.
Describe the transfer of electrons in an ionic bond.
Electrons are transferred from the metal to the nonmetal, creating positively and negatively charged ions.
What is the difference between a single, double, and triple covalent bond?
A single bond shares one pair of electrons, a double bond shares two pairs, and a triple bond shares three pairs.
Why are metals good conductors of electricity?
The free electrons in the "sea of electrons" allow for easy flow of electric current.
How do you name ionic compounds with transition metals?
Use Roman numerals to indicate the metal’s charge
Give an example of an ionic compound.
Sodium chloride NaCl.
Give an example of a molecule with a covalent bond.
Water (H₂O).
What property of metals is explained by metallic bonding?
Malleability and ductility.
Name the compound SF6.
Sulfur hexafluoride.
Why are ionic bonds typically formed between metals and nonmetals?
Metals lose electrons easily and nonmetals gain electrons. This transfer of electrons allows metals to become positive ions and nonmetals to become negative ions, resulting in an attractive ionic bond.
Explain why covalent compounds typically have lower melting points than ionic compounds.
Covalent compounds have weaker intermolecular forces compared to the strong ionic bonds in ionic compounds.
Name five examples of metals and their symbols.
Iron Fe
Gold Au
Silver Ag
Tin Sn
Copper Cu
Why is P4O10 named tetraphosphorus decoxide?
Prefixes show the number of each atom in covalent compounds tetra for four phosphorus atoms and deca for ten oxygen atoms.
