What website to find this information

You can find information about periodic table terms and related concepts on several reliable educational websites. Here are some good resources:

  1. Khan Academy (www.khanacademy.org) - Offers comprehensive lessons on chemistry, including topics related to the periodic table and atomic structure.

  2. Royal Society of Chemistry (www.rsc.org) - Provides detailed explanations and resources on various chemistry topics, including the periodic table and elements.

  3. Chemistry LibreTexts (chem.libretexts.org) - A free online resource that covers various chemistry concepts in depth, including the periodic table and groups of elements.

  4. Periodic Table of Elements (www.ptable.com) - An interactive periodic table that provides detailed information about each element, including its classification and properties.

  5. NASA's Teacher Resources (www.nasa.gov/education) - While primarily focused on space science, it also includes educational materials about elements and the periodic table.

  6. ChemSpider (www.chemspider.com) - A free chemical structure database providing access to millions of chemical structures, properties, and associated information.

These websites are excellent starting points for learning about the terms related to the periodic table and other chemistry concepts.

Define them from each website

I can’t directly access external websites or retrieve information from them in real-time. However, I can provide you with definitions for each of the terms you listed based on general knowledge. You can then use the websites I recommended to find more detailed information and additional resources on each topic. Here are the definitions:

  1. Bohr Model: A model of the atom proposed by Niels Bohr in 1913 that depicts electrons orbiting the nucleus at fixed distances; it introduces quantized energy levels.

  2. Alkali Metals: A group of elements found in Group 1 of the periodic table (excluding hydrogen). They are highly reactive and include lithium (Li), sodium (Na), and potassium (K).

  3. Alkaline Earth Metals: The elements in Group 2 of the periodic table, which include beryllium (Be), magnesium (Mg), calcium (Ca), and others. They are somewhat reactive metals.

  4. Transition Metals: Elements found in Groups 3 to 12 of the periodic table, known for their ability to form variable oxidation states and for their use in various industrial applications.

  5. Metalloids: Elements that have properties intermediate between metals and nonmetals. Common examples include silicon (Si) and arsenic (As). They are typically semiconductors.

  6. Halogens: A group of nonmetals in Group 17 of the periodic table, including fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are known for being highly reactive.

  7. Noble Gases: Elements in Group 18 of the periodic table, such as helium (He), neon (Ne), argon (Ar), and xenon (Xe). These gases are colorless, odorless, and extremely unreactive due to their full valence electron shells.

  8. Lanthanide: A series of 15 elements from lanthanum (La) to lutetium (Lu) in the periodic table. They are f-block elements known for their rare earth properties.

  9. Actinide: A series of 15 elements from actinium (Ac) to lawrencium (Lr) in the periodic table. These elements are also f-block and include radioactive elements like uranium (U) and plutonium (Pu).

  10. Valence Electron: The electrons in the outermost shell of an atom that are involved in forming bonds with other atoms. The number of valence electrons determines an element's chemical properties.
