:N:::N: N has 5 electrons, so two N atoms share their 10 electrons between them as in the above. Notice I have 10 electrons total but each nitrogen atom THINKS it has 8. The atoms make 16 (apparent) electrons out of 8 (real). Neat trick.

Science
With the electrons thing: ionic=one atom gives electrons away to try to have a full outer energy level...after that, the atoms involved in the bond are ions (have + or - charges), and are attracted magnetically because one is positive, and one is negative. This is usually with...

chemistry
The first and fourth carbon atoms are sp2 hybridized. The second and third carbon atoms are sp hybridized. There is no need to assume the hydrogen atoms are hybridized. Hybridization is a scheme to explain the geometry around a central atom bonded to two or more other atoms. ...

4th grade
electricity is electrons. They can be conducted thru metals, but not non-metals. Why? Because metals have atoms that allow electrons to be loosly attached and move, but kinds of atoms that dont allow this movement are without electron flow from atom to atom..they are non-...

No. I don't remember the exact equation but I know the one I wrote for you that evening was correct. This one, the C has an oxidation state of -2 (4H=+4, 1 O = -2 so C must be -2) in CH3OH. It goes to zero on the other side with CH2O so it loses 2 electrons. Mn changes from +7...

Chemistry
A neutral atom of an element has 2 electrons with n=1, 8 electrons with n=2, and 5 electrons with n=3. Write its electron configuration and find: A) atomic number B) total number of s electrons C) total number p electrons D) total number of protons E)Paired electrons F)...

Chemistry
carbon 13 = 6 protons (because of its atomic number) and 7 neutrons) since carbon 13 has 6 protons, it also has 6 electrons to counteract (3.70 x 10^23 atoms)(6 electrons/atom)=?
