Answer: 66
Explanation: To find the mass number you would have to add the number of protons and the number of neutrons.
Because going down a column you are jumping up to the next higher main energy level (n) and each energy level is further out from the nucleus
Answer:
Atomic number=No. of protons=No. of electrons in ground state(unchanged atom)
Atomic number=13=No. of protons
Atomic mass=no. of protons+no. of neutrons=13+14=27
For isotope no. of proton=13(same atomic number but different mass number are isotopes)
no. of electrons=13
no. of neutrons=14+2=16
Explanation:
hope it's help you
I think is False! Because it is not example of a disaccharide it is not saccharin-aspartame molecule.
