My first full wiki!

My first full wiki - Matrix determinants

#Algebra #Matrices #Determinant

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Why iron has sometimes valancies 2 or 3?

sonu chauhan - 6 years, 5 months ago

I don't know how this is related to my note,but I'll be happy to help you and I am very interested in chemistry by the way. The last two orbitals of iron are (4s and 3d) are very close in energy, so sometimes Iron gives up its 2 outer 4s electrons, and sometimes it also gives up an 3d electron m beside the two 4s electrons, because of that Iron ion having either Fe+2 or Fe+3 which are respectively named as ferrous and ferric.
