Intro to Bonding
This term describes the force that holds atoms together in a compound.
What is a chemical bond?
In ionic bonding, atoms of this charge form when a metal loses electrons.
What is a cation?
In metallic bonds, electrons are described as this — not attached to individual atoms.
What are delocalized electrons?
A compound formed by ions that typically forms a crystal lattice
What is a salt/ionic compound?
Name Na₂CO₃.
What is Sodium carbonate
This property measures how strongly an atom attracts electrons in a bond.
What is electronegativity
This rule is used to determine the charge of an ion when writing an ionic formula.
What is the rule of zero charge?
This property of metals is explained by the sea of electrons in metallic bonds.
What is electrical conductivity?
A negatively charged ion formed when an atom gains electrons.
What is an anion?
Write the formula for calcium phosphate.
Ca₃(PO₄)₂
This rule explains why most atoms form bonds — they want 8 electrons in their outer shell.
What is the Octet rule
When naming an ionic compound with a transition metal, you must include this to show its charge.
What is a Roman numeral?
Steel and bronze are examples of this type of metallic mixture.
What is an alloy?
A group of covalently bonded atoms that carries an overall charge.
What is a polyatomic ion?
Name BaCl₂.
Barium chloride
Unlike ionic bonds, these bonds share electrons between atoms.
What is covalent bonds
This type of ionic compound contains a charged group of covalently bonded atoms.
What is a polyatomic ion compound?
This property explains why metals can be hammered into shapes without breaking.
What is malleability?
The regular repeating 3D arrangement of ions in a solid ionic compound.
What is a crystal lattice?
Write the formula for gold (III) carbonate
Au₂(CO₃)₃
"Bonding is a spectrum" means bonds range from this type to this type
What is covalent to ionic?
The properties of NaCl differ greatly from sodium and chlorine alone. This illustrates what chemistry idea?
What is that a compound's properties differ from its elements?
This is the key feature that makes metallic bonds unique from ionic and covalent bonds.
What is the sea of freely moving delocalized electrons?
A metal combined with at least one other element to achieve specific properties.
What is an alloy?
Name Mn(OH)₂.
Manganese (II) hydroxide
