Q. What 2 subatomic particles make up the mass of an element?
Mass: The majority of an atoms’ mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10-31 kg and a size too small to be measured by current techniques.
Q. Which two of the subatomic particles contribute most to the mass of an atom?
Protons are massive particles with unit positive electric charge; neutrons are massive particles with NO electric charge. Together these constitute MOST (>99.9%) of the mass of the atom.

Q. Which two subatomic particles affected the mass number?
The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess. Together, the number of protons and the number of neutrons determine an element’s mass number.
Q. What subatomic particle determines the mass of an atom?
proton
Q. Where is a proton located?
nucleus
Q. What is Proton made up of?
Protons are positively charged particles found within atomic nuclei. Three quarks make up each proton — two “up” quarks (each with a two-thirds positive charge) and one “down” quark (with a one-third negative charge) — and they are held together by other subatomic particles called gluons, which are massless.
Q. Why is Planck length smallest possible?
So why is the Planck length thought to be the smallest possible length? The simple summary of Mead’s answer is that it is impossible, using the known laws of quantum mechanics and the known behavior of gravity, to determine a position to a precision smaller than the Planck length.
Q. How small is a Planck?
Then keep going, a hundred million times smaller still, and you finally hit bottom: This is the Planck length, approximately 1.6 x 10-35 meters, believed by physicists to be the shortest possible length in the universe.
Q. Does the Higgs boson exist?
A particle with a mass of 125 GeV was discovered in 2012 and later confirmed to be the Higgs boson with more precise measurements. The Higgs boson is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory.
Q. What is the smallest element known to man?
Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
