Plse help i need so much help on thes questions i am SO confused

10. What is stucturally diffrent between an atom and an ion?

13. If prontons and neutrons have the same mass wat is the approximate mass of apronton and nuetronin atomic mass units (amu)?

16. What is the charge on every atom? Why is this a charge? How do you determine the charge on a ion?

Plse help and thx a million

    10. What is stucturally diffrent between an atom and an ion? Atoms lose or gain electrons to become positive or negative ions.

    13. If prontons and neutrons have the same mass what is the approximate mass of apronton and nuetronin atomic mass units (amu)? Protons (notice the correct spelling) and neutrons, on the relative scale, have a mass of 1

    16. What is the charge on every atom? Why is this a charge? How do you determine the charge on a ion? The charge on all atoms is zero because atoms have equal number of protons (with a positive charge) and neutrons (with a negative charge). The charge of an ion is determined by counting the excess of electrons or protons. An excess of 1 proton is +1 charge, an excess of 2 protons is +2 charge, an excess of 2 electrons is -2 charge, etc.
