Summary Introduction

To review:

Why the weight of electrons is ignored when we consider atomic mass.

Introduction:

Atoms are made up of three particles – protons, neutrons and electrons.

Expert Solution & Answer

Explanation of Solution

Atoms are made of the positively charged protons, neutral neutrons and negatively charged electrons. The protons and neutrons have similar weight and sit at the core of the atom (the nucleus). However, the weight of an electron is less than one-twentieth of 1% of the weight of a proton. The weight of the electrons is insignificant in comparison with that of the protons and neutrons. This is why the weight of the electrons is ignored.

Conclusion

Electrons weigh less than one-twentieth of 1% of the weight of the protons. The weight of the electrons is insignificant in comparison with that of the protons and neutrons. This is why the weight of the electrons is ignored.

According to chemist John Dalton, if one mole of nitrogen is combined with three moles of hydrogen to form one mole of ammonia (knowing that nitrogen, with an atomic number of 7, has an atomic mass of 14, and hydrogen, with an atomic number of 1, has an atomic mass of 1), then this compound will have an atomic weight (or molecular mass) of: 14 grams per mole (14 daltons) 17 grams per mole (17 daltons) 20 grams per mole (20 daltons) 22 grams per mole (22 daltons) 43 grams per mole (43 daltons)
