Answer:
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Answer:
the answer is 74.03%
Explanation:
Add all the masses together, M of C = 120.1, M of H = 14.4 and M of N = 28.02. Adding all those together will give you the mass of the compound, then u divide the mass of carbon by the mass of compound and multiply by 100 to get the percent by mass.
120.1 + 14.4 + 28.02 = 162.26
120.1/162.26 x 100 = 74.03%
Answer:
+5
Explanation:
You use the rules for oxidation numbers to calculate that the oxidation number of N is +5.
Chemical Potential Energy is released when chemical bonds between atoms are broken (like covalent and ionic) and is released mainly as thermal
Elastic Potential is released when the molecules in the material are allowed to go back to there original form, and is released mainly as kinetic
It will belong to the metals because metals bond with nonmetals like chlorine to form ionic compounds
