please Professor Eman about Lewis structure it appears to be tricky with complex molecules or molecules with a charge like NO3- or O3 or Hno3 please is there some tricks to draw it for every molecule without difficulties and thanks for your time and your help

Hi! I have an old one in a general chemistry 1 playlist but plan on making an updated one soon my friend!

In the case of Nb2O5 a transition metal and nonmetal --> we are using type II binary compound because transition metal has many ionic charges thus indicating we have to use roman numerals to specify. Does this apply to only transition metals in type II? Also I thought it would be nice, if you could review element charges (especially in periodic table), as they are helpful in formulating chemical equations.

1:05:27 common monatomic ions 1:22:00 common polyatomic ions Some key points to remember: 1. Group 1 (Alkali Metals): These elements (e.g., lithium, sodium, potassium) typically have a +1 charge. They readily lose one electron to achieve the electron configuration of the nearest noble gas. 2. Group 2 (Alkaline Earth Metals): Elements in this group (e.g., magnesium, calcium) commonly form ions with a +2 charge by losing two electrons. 3. Transition metals: Variable charges 4. Group 16 (Chalcogens): Oxygen, sulfur, and other elements in this group typically form -2 ions by gaining two electrons. 5. Group 17 (Halogens): These elements (e.g., fluorine, chlorine) typically gain one electron to form -1 ions. 6. Group 18 (Noble Gases): Noble gases generally do not form ions under normal conditions because they already have a stable electron configuration.
