There are 22 neutrons in an argon atom. you simply subtract the proton count (atomic number) from the average atomic mass. WORK: 40-18=22
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.
Answer:
Chemical equation showing the reaction of Methylamine with water:
CH3NH2 + H2O ==>> CH3NH3+ + OH–
Answer:
Mass is conserverd
Explanation:
Any chemical reaction must follow the law of conservation of mass. Meaning that mass cannot be created nor destroyed. Since all chemical reactions must follow this law, no matter what reaction happens, mass is conserved.
