Determine why electrons do not need to be considered when comparing the masses of atoms. The mass of an electron is so small that it is insignificant compared to the mass of protons and neutronsThe negative charge of electrons makes it too hard to calculate

How can you determine an atom's atomic mass?aAdd the protons and electrons togetherbAdd the protons and neutrons togethercAdd the electrons and neutrons togetherdIt cannot be determined

Which best describes the mass of protons, neutrons, and electrons?A.Neutrons and protons have a much larger mass than electrons.B.Protons have a much larger charge than neutrons and electrons.C.Electrons have a much larger mass than protons and neutrons.D.Neutrons have a much larger mass than protons and electrons.

Protons...A..are positively charged and have roughly the same mass as electrons.B..are negatively charged and have roughly the same mass as electrons.C..are positively charged and have roughly the same mass as neutrons.D..are negatively charged and have roughly the same mass as neutrons.

Protons and neutrons are found in the nucleus of an atom. Traveling around the nucleus are fast-moving particles called electrons. Each electron has a negative electrical charge. An electron is much smaller and lighter than a proton or a neutron.Which of the following statements are true? Select all that apply.All of an atom's electrons are located outside its nucleus.An electron has a negative electrical charge.A proton is the same size as an electron.Submit

How is the atomic mass of an element determined?By adding the number of protons and electronsBy the number of protons in the nucleusBy the number of electrons in the outer orbitalsBy adding the number of protons and neutrons in the nucleus
