How to predict which elements will have a certain oxidation state?

Click For Summary
SUMMARY

This discussion focuses on predicting the oxidation states of elements, specifically identifying those with maximum oxidation states of +6, +7, and +8. The key method mentioned is counting valence electrons, which is crucial for determining oxidation states based on an element's position in the periodic table. The conversation highlights the challenge of memorizing oxidation states alongside the periodic table for upcoming tests, emphasizing the importance of understanding the relationship between valence electrons and oxidation states.

PREREQUISITES
  • Understanding of the periodic table and element positioning
  • Knowledge of valence electrons and their role in oxidation states
  • Familiarity with basic chemistry concepts, including oxidation and reduction
  • Ability to memorize and recall elemental properties
NEXT STEPS
  • Study the oxidation states of transition metals and their common maximum states
  • Learn about the oxidation states of nonmetals and their variations
  • Explore the concept of electronegativity and its impact on oxidation states
  • Review examples of elements with known oxidation states in chemical reactions
USEFUL FOR

Students preparing for chemistry exams, educators teaching oxidation states, and anyone interested in deepening their understanding of elemental chemistry.

Homework Statement



I have a test coming up and some of the practice questions were things like "Name 6 elements with a maximum oxidation state of +7" or some other number like +8, +6, etc. How do I go about doing this?

The Attempt at a Solution



There is the obvious trick of counting valence electrons, but past that how do I figure stuff like this out? How do i know which noble gases have what oxidation states?

I already have to memorize the periodic table for this test, I'd hate to have to memorize all the random oxidation states of elements too.

If you know PT, valence electrons depend on the position of the element.
