Study Notes
Periodic Table Overview
- Dmitri Mendeleev is known as the father of the periodic table, credited with organizing elements based on their properties.
- The periodic table consists of vertical columns called groups, which categorize elements with similar characteristics.
Groups and Elements
- Alkali metals are located in Group 1A of the periodic table, known for their high reactivity.
- The elements in Group 7A (17) are known as halogens, recognized for their aggressive chemical behavior.
- Group 2A is referred to as alkaline earth metals, consisting of reactive metals.
Transition Metals
- Transition elements include metals like iron (Fe) and nickel (Ni), known for having d electrons.
- Transition metals are categorized due to their properties, such as being good conductors of electricity and heat.
Atomic Structure
- The atomic number of an element represents the number of protons and is also equal to the number of electrons in a neutral atom.
- Isotopes are variations of an element that have the same number of protons but differ in neutron count.
Electron Configuration
- Silicon has the electron configuration of 1s² 2s² 2p⁶ 3s² 3p², outlining its distribution of electrons in atomic orbitals.
Elemental Symbols
- Element symbols consist of a capital letter, and potentially a lowercase letter, derived from the element's name (e.g., Ag for silver, Au for gold, Cu for copper, Zn for zinc).
Other Key Facts
- The Lanthanide series is found in Period 6, consisting of elements with similar properties.
- The boundary that separates metals from nonmetals in the periodic table is represented as a zigzag line.
- Carbon, silicon, nitrogen, and oxygen are classified as nonmetals, which are essential for life and various chemical processes.
- The last natural element on the periodic table is Uranium, symbolized as U.
- Horizontal rows in the periodic table are called periods, indicating the energy levels of electrons in the elements represented.
