1.1 Particle Theory and Bonding Flashcards
Element
A substance that cannot be chemically broken down into a simpler substance
Compound
A substance containing two or more elements chemically bonded together
Molecule
A group of atoms covalently bonded together
Atom
The smallest particle an element can be divided into and still be the same substance
Kinetic Particle Theory (Particle Theory)
The theory of how particles (such as atoms and molecules) move in relation to each other and the amount of energy within the system
Water Vapour
Gaseous phase/ state of water; produced when liquid water evaporates or boils
Proton
A positively charged subatomic particle contained within the nucleus of an atom
Neutrons
A neutral subatomic particle contained within the nucleus of an atom
Electron
A negatively charged subatomic particle that orbits the nucleus of an atom
Nucleus
The positively charged central core of an atom that is made of protons and neutrons
Shells
Each of a set of orbitals around the nucleus of an atom that can be occupied by electrons
Atomic Number
The number of protons contained in the nucleus of an atom
Bond
A strong force of attraction holding atoms together in a substance
Emergent Properties
Characteristics that are present within a compound or molecule of two or more different elements that those elements do not possess on their own
Covalent Bond
Chemical bond that involves the sharing of electron pairs between atoms
