Lesson 1 Flashcards
Molecule
Two or more atoms that covalently bond together to form a unit.
What is the mole?
The SI base unit used to measure the amount of a substance.
1 mole is the amount of atoms in 12g of pure carbon-12, or 6.022 *10^23 representative particles which is any kind of particle - an atom, a molecule, a formula unit, an electron, an ion, and so on.

A representative particle is any kind of particle, such as an atom, a molecule, a formula unit, an electron, or an ion.
A representative particle is any kind of particle, such as an atom, a molecule, a formula unit, an electron, or an ion.
water, copper, and salt are one-mole quantities. Each one has a different representative particle: molecules of water, atoms of copper, and formula units o NaCl.
