Technically speaking, the neutrons do, as they weigh slightly more than protons. However, there may be more protons than neutrons in the nucleus. It will depend on the isotope.

Which of the subatomic particles has a negative charge is found outside of the nucleus and has almost no mass?
THe electron!
How many subatomic particles are there in iodine?
It would depend on how much iodine is present. The greater the mass the more particles there would be
What are the subatomic particles found outside of the nucleus?
These particles are called electrons, with a negative electrical charge and a very small mass.
Which two subatomic particles have about the same mass?
Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nucleus of helium-4 is composed of two protons and two neutrons.
Is an electron a sub atomic particle in the nucleus that is attracted to electrons?
no. ions are made of relatively whole atoms (plus or minus a few electrons)
What are the subatomic particles with no mass called?
All subatomic particles have mass.
Does subatomic particles have the smallest mass of any subatomic particle?
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
What are the features of the subatomic particles?
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
What subatomic particles are similar in mass?
neutrons and protons
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
What subatomic particles has appreciable mass and lacks a charge?
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
What subatomic particles contribute to the mass of?
The atomic mass is the sum of the number of protons and the number of neutrons found in each atom of that element (electrons do not contribute). They are sometimes seen on periodic tables to have a decimal in the atomic number, this is for elements with more than one common isotope (an isotope of an element is the same number of protons but with a different number of neutrons), in which case an average of the common isotopes can be used.
Which statement about subatomic particles is not true?
Subatomic particles are the same size as basketballs.
Of the three main subatomic particles the has the least mass?
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or Atomic Mass units.
What subatomic particle contributes alomst no weight to an atom?
The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
