Which two particles make up most of the mass of a hydrogen-2 atom?
The two particles that make up most of the mass of a hydrogen-2 atom are the proton and neutron. The proton has a positive charge and is responsible for defining the element, while the neutron has no charge and helps stabilize the nucleus.
Is mass used as a method of counting atoms?
Mass is not used as a method of counting atoms directly. Instead, the atomic mass unit (amu) is used to measure the mass of individual atoms relative to the mass of a carbon-12 atom. The mole is the unit used to count atoms, with 1 mole containing Avogadro's number of atoms.
Which two subatomic particles make up most of the atoms mass?
It is usually considered to be neutrons and protons that hold most of an atom's mass, however there is one theoretical subatomic particle that is used to help explain mass, called the higgs boson particle.
Most calcium atoms have an atomic number of 20 and a mass number of 40 but some calcium atoms have a mass number of 48 What word could you use to describe these two kinds of calcium atoms?
Isotopes. Calcium atoms with a mass number of 40 represent the most common isotope, while those with a mass number of 48 are a less common, but still natural, isotopic form of calcium.
Rutherfords gold foil experiment led to the discovery of the?
Nucleus - Rutherford fired particles at gold foil, and most went straight through. This showed that most of atoms are empty, and that most of the mass only occupies a small part of the atom. This part is known as the nucleus.
Which particles account for most of an atoms mass?
Protons and neutrons are the particles that account for most of an atom's mass. Electrons, which have much less mass, play a negligible role in the overall mass of an atom.
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
Which subatomic particles account for most of an atoms mass?
The up and down quark accounts for most of an atoms mass. Two up quarks and one down quark forms a proton, and one up quark and two down quarks forms a neutron. Protons and neutrons form the nuclei of atoms, and comprise most of their mass, along with the binding energy holding them all together.
What subtomic particle account for most all of an atoms mass?
Protons and neutrons, which are found in an atom's nucleus, account for most of an atom's mass. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
What 2 particles have similar masses?
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
Which two particles make up most of the mass of a hydrogen-2 atom?
The two particles that make up most of the mass of a hydrogen-2 atom are the proton and neutron. The proton has a positive charge and is responsible for defining the element, while the neutron has no charge and helps stabilize the nucleus.
Which two subatomic particles make up most of the atoms mass Where are they located?
These particle are neutrons and protons; they are located in the atomic nucleus.
What are the particles in the atom that account for most of the mass of the atoms are protons are?
Neutrons is the answer. Both protons and neutrons have almost equal mass and concentrated in nucleus. Electrons have negligible mass as compared to mass of protons and neutrons and such minor figures are discarded in physics as much as mass isconcerned. Mass of electron is 1/1836 as compared to proton. But electric charge wise 'both' are equal and apposite.
What is pair of particles with nearly the same mass?
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
What is the most of the mass of an atoms?
The nucleus.
Most of the mass of the atom is where?
More then 99% of an atoms mass is in the nucleus.
What does most of the atoms mass come from?
the nucleus
