General Chemistry Flashcards
Recognize the chemical structure and relationships
What are the group and row classifications in the periodic table? Give details on their phases.

The chart shows vertical groups and horizontal rows and are identified in the following:
1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A (Main Groups/ representative elements)
1A - Alkali metals (except hydrogen) Highly reactive with water, k or RB violate with water.
2A - Alkali Earthmetals
3A, 4A, 5A - no name
6A - chalcogens
7A - Halogens
8A - Noble gases or inert gas (don’t react with anything)
B group elements are the transition metals (includes elements in the third row between all main groups)
Last two detached horizontal rows are also transition metals
Lanthanides - 1st detached row
Actinides - 2nd detached row
Phases:
At room temperature between (20 degrees celsius to 25 degrees celsius) all elements are SOLIDS except for Mercury (in a thermometer) and Bromine are Liquids.
Hydrogen, Nitrogen, Chlorine, Fluorine, Oxygen, and all the Noble Gases are GASES.
Parts of Atoms (Electrons)
