. ✔
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.
There are 1.50 x10^6 atoms of nitrogen in 10 grams of NH4NO3. You convert the grams to moles first and then using the definition of a mole you determine the number of molecules.
the answer is because when you research that would be the answer
Answer:
Dalton law states that the partial pressure of a gas in a mixture of gases is equal to the total pressure of the mixture.
