When I consider how much money schools invest in gyms, and the quality of instruction is so poor, shouldn't the money be invested more wisely?
What is in New Year's Eve rockets and creates the colorful effects and that the pieces fly so far away?
First of all, sorry if this is a stupid question, but we haven't been studying chemistry for very long and I'm trying to get a little bit of preparation🙃 We did an experiment on reduction where iron and CuO react to form FeO and Cu. I'm just wondering if the molecular formulas are correct (probably…
I'm 14 years old. I'm currently in upper secondary school (AHS) and I've realized that I don't want to take the Matura or continue on to upper secondary school because the subject matter doesn't suit me. The only reason I wanted to do upper secondary school was because most of my family did. Recently, I've…
He always goes to the disco on Saturdays and he doesn't care what people think of him. He's always drinking, my father did, and he once smuggled wine into a beer tent because beer costs too much. My friend always says your father has no respect, he's an alcoholic and he has to behave, but…
Hello everyone ! 🙂 The question is above. Here's another example:

With main group elements, this is quite simple.
Metals they have always positive Charges in metal-non-metal compounds. They give Electrons. They’re oxidized.
Non-metals have always been negative Charges in metal-non-metal compounds. (External hydrogen, which is usually simply positively charged).
The size of the charge corresponds to the main group number of metals. For example, Mg is in the II main group and is therefore charged in compounds 2+. Sodium is accordingly 1+ or simply + charged.
Take non-metals Electronics in responses on. You will reduced. They take up so many electrons until they have 8 electrons in the outer “electron shell”. This means their charge = main group number – 8. For example, oxygen O is in the VI. Main group. Charge is therefore 6-8 =-2.
The charges are… +1, +3, -/+4, -3, -2, -1, 0.
