Atom is smallest particle
Element is a substance made of only 1 atom.
Proton: how many protons determine what element it is (atomic number)
Atomic number: # of protons in atom
Mass is amount of matter in body.
Protons have high mass of 1 amu (atomic mass unit)
Neutrons: in nucleus with protons, have neutral charge
Isotopes: different number of neutrons, but same # of protons
Isotopes symbols show proton # + neutron # in atom at top, below # of proton
Eletron: has negative charge and float in orbit around nucleus
Lesson: 2
Neutral Atom: have same number of protons and electrons
Ion: has a charge (+ or -)
Ion is represented in atomic symbol as superscript + or – and value (-3 or +2)
Lesson 3
Periods: Horizontal lines on the periodic table that make rows of elements.
Groups: Vertical lines on the periodic table.
The groups have many different names which are Alkali Metals, Alkaline Earth Metals, The Boron Family, The Carbon Family, The Nitrogen Family, The Oxygen Family, The Halogens, and The Noble Gases.
Metalloid: An Element that is a mix of nonmetals and metals.
Answer: Flourine.
Answer: Potassium.
Lesson 4
Properties of Metals: solid, luster, malleability, conductivity
Left side of Periodic table are metals, right side non-metals
Alkali Metals and earth metals at top of table
Transition metals, Actinides & lanthanides are in middle of table
Reactivity: alkaline are most reactive
Lesson 5
Metalloid examples: silicon, boron, arsenic
Listed on table like a staircase between metals and non-metals
Valence Electrons: found in outermost electron shell
Lesson 6
Noble gas: ordorless gass that doesn’t react.
Ionic compound: positve and negative charged metal compound
Covalent bond: Sharing of electrons in a bond
Diatomic molecules: two of the same elements are bonded together
Lesson 7
noble gasses like radon, neon, argon, krypton
physical properties: boiling point, melting point, solubility
chemical properties: color, ordor, flamibility and reactivity
fractional distillation: separate noble gases using heat
liquefaction of gases: pressure to create condensation to separate gas
