- 1AtomSmallest particle of an element that retains chemical properties of the element
- 2Elementsubstance that cannot be broken down into simpler substances through chemical reaction
- 3What is the charge of a proton? a neutron? electron?+1
0
-1 - 4Isotopesatoms of the same element that have different numbers of neutrons in the nucleus
- 5Isoelectronic Ionsions having the same number of electrons (e-1s)
- 6Ground Statelowest state of energy for particle
- 7Excited Stateany energy level above ground state
- 8Orbitalregion in space where there is a maximum probability of finding an electron
- 9S Subshell1 orbital
2 max electrons - 10P Subshell3 orbitals
6 max electrons - 11D Subshell5 orbitals
10 max electrons - 12F Subshell7 orbitals
14 max electrons - 13Aufbau's Principlemethod of showing how atomic orbitals are filled in a definite order to give lowest energy arrangement possible
- 14General Properties of MetalsMalleable, Ductile, Lustrous
Oxidize to form positive ions
Conduct heat and electricity - 15Properties of Alkali MetalsMost reactive metal family
Form alkaline solutions when reacted with water
Reactivity increases down group - 16Properties of Transition MetalsUsually form colored solutions
Have several possible oxidation states
Act as catalysts
Silvery-blue at r.t.p. (except copper and gold)
Solid ar r.t.p. (except mercury)
Magnetic - 17General Properties of Non-MetalsDo not conduct electricity
All element gases included here
Hydrogen placed with metals, is also a non-metal - 18General Properties of HalogensExist as diatomic molecules
Most commonly used to form salts
Reactivity decreases down group - 19Atomic Radius TrendsDown a Group - Decreases, New shells added, effective nuclear charge decreases
Up a Group - Increases, Atomic radius decreases, shielding effect constant - 20Ionic Radiusdescribes size of ions
Metal - loses electrons. lose a shell and ionic radius less than atomic radius
Non-Metals - gain electrons. Gain a shell and ionic radius greater than atomic radius - 21Electronegativitystrength with which atoms attract valence electrons in a chemical bond.
Increases across period
Decreases down period - 22Alpha ParticleIdentity - Helium Nucleus

Ionizing Power - High - 23Beta ParticleFast moving electron, 0/-1e symbol, 0 charge, 1/1840 mass, fast, varying energy, stopped by few mm of aluminum, 12m range, low ionizing power
- 24Gamma Rayelectromagnetic, y, 0 charge, V of light, varying energy, stopped by few cm of lead, no specific range, very low ionizing power
- 25Alpha Decayalpha particle, 2+ charge, -4 change in mr, -2 change in ar
- 26Beta Decaybeta particle, 1- change, 0 change in mr, +1 change in ar
- 27Gamma Raygamma particle, 0 charge, 0 change in mr, 0 change in ar

- 30Law of Conservation of Matterin all forms of decay neither protons nor neutrons are created nor destroyed
- 31Fusion2 smaller nuclei form a larger nucleus
- 32Fissiona large nucleus splits into 2 smaller nuclei
