Study Notes
Periodic Table Basics
- A family refers to a vertical column in the periodic table, where elements share similar properties.
- A period is a horizontal row in the periodic table, indicating the number of electron shells around an atom's nucleus.
Element Symbols
- Magnesium symbol: Mg
- Potassium symbol: K
- Iron symbol: Fe
- Copper symbol: Cu
Element Names
- C: Carbon
- Cl: Chlorine
- Au: Gold
- Sr: Strontium
Period Classification of Elements
- He (Helium) is in Period 1.
- Ge (Germanium) is in Period 4.
- Rb (Rubidium) is in Period 5.
- I (Iodine) is in Period 5.
Group Classification of Elements
- Sulfur (S) is in Group 16 (Chalcogens).
- Ca (Calcium) is in Group 2 (Alkaline Earth Metals).
- Iodine (I) is in Group 17 (Halogens).
- Fe (Iron) is in Group 8 (Transition Metals).
Specific Elements by Characteristics
- Halogen: Chlorine (Cl)
- Chalcogen: Oxygen (O)
- Alkali metal: Sodium (Na)
- Boron: Boron (B)
- Lanthanide series: Neodymium (Nd)
- Alkaline Earth metal: Barium (Ba)
- Transition metal: Nickel (Ni)
- Noble gas: Neon (Ne)
Atomic Characteristics
- Atomic symbol for silver: Ag
- Atomic mass of mercury: 200.59 u
- Ni symbol represents Nickel.
- Element with atomic number 17: Chlorine (Cl).
- Two transition metal symbols: Cu (Copper), Ag (Silver).
- Group for Cu, Ag, and Au: Group 11.
- Two noble gases: Neon (Ne), Argon (Ar).
- Symbols for two halogens: F (Fluorine), Cl (Chlorine).
- Atomic number 74 corresponds to Tungsten (W).

Atomic Mass Calculations
- Oxygen (O): Atomic mass approximately 16, neutrons = 8 (16 - 8).
- Helium (He): Use periodic table for atomic number and mass.
- Carbon (C): Use periodic table for atomic number and mass.
- Aluminum (Al): Use periodic table for atomic number and mass.
- Calcium (Ca): Use periodic table for atomic number and mass.
- Sodium (Na): Use periodic table for atomic number and mass.
- Potassium (K): Use periodic table for atomic number and mass.
- Nitrogen (N): Use periodic table for atomic number and mass.
- Silicon (Si): Use periodic table for atomic number and mass.
- Iron (Fe): Use periodic table for atomic number and mass.
- Hydrogen (H): Use periodic table for atomic number and mass.
Element Protons and Electrons
- Calcium: Protons = 20, Electrons = 20.
- Gold (Au): Protons = 79, Electrons = 79.
- Copper (Cu): Protons = 29, Electrons = 29.
- Iron (Fe): Protons = 26, Electrons = 26.
Comparative Characteristics
- Mercury has more protons (80) than tin (Sn: 50) and thus more electrons as they are equal in number.
- Mercury is heavier than tin.
- Potassium has more electrons than neon; K has 19 electrons vs. Ne's 10.
- Hydrogen has fewer electrons than uranium (U), which has 92 electrons.
- Sulfur (16 protons) has fewer protons than iodine (53 protons).
