Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
What are relative sizes of a subatomic particle?
It is way smaller (9.11x10^-31kg) than a proton or neutron (1.67x10^-27kg)
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

How do you find how many protons electrons and neutrons are in an atom?
The amount of protons is the same as the Atomic Number of the atom. Also the same goes for the amount of electrons. The number of neutrons in an atom would be the atomic mass minus the number of protons, neutrons, or atomic number. (it doesn't matter which of the three you use because they are all the same number) For example Titanium has an atomic number of 22, protons 22, and electrons 22. The atomic mass is 47, so to find the amount of neutrons you would take the atomic mass (47) minus the atomic number, protons, or electrons (22). So this would be your equation... Atomic mass - electrons (or whichever you choose) equals number of neutrons. So-> 47-22=25 neutrons.
What statement is true about atoms protons neutrons and electrons?
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
How do the circles represent the different parts of an atom?
They don't, unless you mean the smaller ones on the larger ones. The larger, uncoloured circles represent the orbital paths of the electrons of the atoms. The smaller, coloured circles represent the different parts of the atom, like the protons, neutrons, and electrons.
Is a calcium atom larger than a barrium atom?
Calcium contains 20 protons, 20 neutrons and 20 electrons (on average). Barium has 56 protons 81 neutrons and 56 electrons (again, on average). So, Barium is much larger.
Are protons bigger than electrons?
Yes, protons are larger than electrons.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
Particles that make up an atom?
There are three particles that make up an atom: electrons, protons, and neutrons. The electron is a tiny, light particle that has a negative charge. The proton is larger and heavier and has a positive charge. The neutron is large and heavy just like a proton, but this particle does not have any charge at all.
What is the same between neutrons and electrons?
When the number of electrons and neutrons are the same, it means that the number of protons will also be the same amount. For example a nitrogen atom has 7 electrons and 7 neutrons, this means that the number of protons will also be 7.
Are protons bigger than neutrons?
Yes, neutrons are larger than protons.
