Protons and neutrons have about the same mass, but electrons are much, much lighter.
A neutron and a proton almost have the same mass. A neutron and 1,840 electrons almost have the same mass.
no. -------------- In atoms, only the Protons count as atomic number The neutrons and the protons together is as the atomic mass
All have spin one-half. Protons have a charge of positive one; electrons, negative one; neutrons, neutral. Protons and neutrons have about the same mass; electrons are much less massive. Protons and neutrons have an internal structure -- ie, they are composed of quarks -- while electrons are just themselves. The first two are "hadrons" and the latter is a "lepton."
um if i remember correctly an electron has 1840 times less mass than a proton and an electron + a proton makes a neutron so a neutron is one 1840th more hevyer than a proton :P esther says: that is rude so the correct answer is no
electrons are the same as protons
The Atomic Mass is equal to the number of protons and electrons that an element has.
Electrons.
The number of protons for any element is the atomic number. The number of electrons is equal to the number of electrons. To find the number of nuetrons you must subtract the atomic number from the mass number mass number-atomic number= number of nuetrons protons=electron the number of protons in the element aluminum is 13. The number of electrons is 13.
Protons and neutrons have almost the same mass.
No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.
The number next to the isotope is the mass number- They all have different masses because they have different numbers of neutrons, but the same amount of protons (Remember protons + nuetrons = mass)
Electrons are very light. Protons are approx. 1800 X the mass (rest mass to be presice). Neutrons are about the same mass a protons. So the mass of all the electrons has little effect.
