Study Notes
Periodic Table Basics
- Vertical columns are known as groups, while horizontal rows are called periods.
- The majority of elements are classified as metals.
Classification of Elements
- Elements touching the zigzag line are identified as metalloids.
- Non-metals occupy the upper right corner, with the top element being noble gases.
- Alkali metals are found in the first group, characterized by having one outer shell electron and high reactivity.
- Alkaline earth metals reside in the second group, containing two outer shell electrons and are also reactive.
- Transition metals comprise groups 3 to 12, showcasing a range of useful properties.
- Group 17 elements are referred to as halogens, meaning "salt formers."
- Group 18 consists of noble gases, known for being inert and unreactive due to their complete outer electron shells.
Special Periods
- The first period at the bottom of the periodic table is called the lanthanides.
- The second bottom period is known as the actinides.
Atomic Structure
- The positively charged particle in an atom's nucleus is a proton.
- The neutral particle in the nucleus is called a neutron.
- The negatively charged particle located outside the nucleus is an electron.
Groups and Reactivity
- Groups 1 and 2 contain highly active metals that are typically found in compounds rather than in pure form.
- Noble gases achieve stability with a complete set of electrons, adhering to the octet rule; having eight valence electrons prevents them from bonding.
- Radon is the noble gas with the most energy shells.
Element Comparisons
- Aluminum has more energy than Boron.
- Hydrogen is classified as a non-metal, despite its placement in group 1.
- The classification of elements like arsenic (Group 15, period 4) can be determined by their positions.
Neutrons and Atomic Mass
- The number of protons in the element located in Group 2, period 7 is associated with Radium.
- For Bromine, the atomic composition includes 35 protons, 35 electrons, and approximately 45 neutrons.
- The atomic number corresponds to the number of protons.
Valence Electrons
- Group number equals the number of valence electrons; for groups 13-18, subtract 1.
- Bromine has 7 valence electrons.
- Valence electrons are crucial for determining how elements bond.
Specific Element Details
- Silicon is categorized under the Carbon Family in period 3.
- Nitrogen is recognized as a Group 2 element with more protons than Carbon but fewer than Oxygen.
- Strontium lies in the alkaline earth metals, having a higher atomic number than Rubidium but fewer neutrons than Rhodium.
- Zinc has an atomic number greater than that of Copper but less than Gallium.
- Calcium is a Group 2 element with fewer protons than Bromine but more than Sulfur.
- Magnesium features three energy levels and two valence electrons.
- Boron holds three valence electrons and fewer protons than Magnesium.
- Helium is the smallest noble gas, while Radon has the most neutrons among noble gases.
- Hydrogen is the sole non-metal located on the left side of the zigzag line.
- Neon belongs to Group 18 and possesses two electron shells.
- Iodine, belonging to the halogen family, has five energy levels.
