I believe the four series you are looking for are straight-chain alkanes, alkenes, and alkynes, and cycloalkanes. These all have the same repeating of CH2 as the base group, while alkenes have a double bond somewhere in the molecule, and alkynes a triple somewhere.
One molecule of N2O4 contains
two nitrogen
four oxygen
Answer:
I interpret the answers as being nonmetallic and metallic.
Explanation:
Nonmetals are in groups 14 - 18. Electronegativity is referred to as the want to attract electrons to an atom. Noble gases (group 18) have eight valence electrons in their outer subshells and are therefore atomically stable. Elements with only 7 valence electrons are very electronegative because they desire to obtain an electron to reach stability more than a group 2 element would (they are more likely to drop electrons by giving away in order to reach atomic stability of a group 18 element). This coincides with electron configuration, which is a very lengthy topic to cover. You can conduct more research if you would need it.
That is called an unsaturated solution
Answer:
Below!
Explanation:
Isotopes are elements with a similar chemical makeup and the same atomic number, but a different atomic mass and number of neutrons . An example of this would be carbon-12, carbon-13, and carbon-14. Three isotopes of the element carbon that have the same 6 protons but have a different neutron count. A simple way to explain isotopes would be to say that they are just different "versions" of an element.
