Question

hello! In the textbook , the nucleon number is at the top & the proton number is at the bottom. However its the opposite way in the periodic table. Does it matter where the proton & neutron numbers are place at?

Answer 1

Yes it matters, because for instance you asked to calculate the mass number, it will help you to use the correct proton and neutron number. Proton number are the same with atomic number

Answer 2

For the sake of knowledge and to avoid ambiguity, YES it does matter.

Step-by-step explanation:

Proper representation of the mass number and atomic number of chemical elements is key or important. The periodic table is the standard arrangement of chemical elements by atomic number, electronic configuration and chemical properties in a tabular form.

Furthermore as a rule, it should be noted that the mass number (nucleon number) is always larger than the atomic number(number of proton)
