Study Notes
Active Metals and Nonmetals
- Most active metals are located in the lower left section of the periodic table.
- Most active nonmetals are found in the upper right section.
Atomic Size Trends
- Atomic size decreases from left to right across a period due to increased nuclear charge.
- Atomic size increases as you move down a group, influenced by increasing energy levels.
Ion Size Differences
- A negative ion (anion) is larger than its parent atom.
- A positive ion (cation) is smaller than its parent atom.
Ionization Energy Trends
- First ionization energy increases from left to right across a period as positive charge of the nucleus increases.
- First ionization energy decreases as you go down a group.
Electronegativity
- The highest electronegativity is found in the upper right of the periodic table.
- The lowest electronegativity is located in the lower left.
Groups and Categories of Elements
- Group 1 elements are known as Alkali metals.
- Group 2 elements are referred to as Alkaline metals.
- Groups 3-12 are called Transition metals.
- Group 17 elements are classified as Halogens.
- Group 18 elements are termed Noble gases.
Element Properties Across the Periodic Table
- As you move from left to right, elements transition from metals to nonmetals.
- Elements in a group share a similar number of valence electrons, influencing their chemical behavior.
- Elements across a series maintain the same number of principal energy levels.
Transition Elements Characteristics
- Transition elements fill the d and f sub-levels during their electron configuration.
Element Composition
- A colored ion usually indicates the group classification of the element.
- With descending groups, elements tend to become more metallic in character.
- The majority of elements in the periodic table are classified as metals.
Element Arrangement and Properties
- The elements in the periodic table are organized by increasing atomic number.
- A metalloid possesses properties of both metals and nonmetals, highlighting versatility in behavior.
