What are the particles in the atom that account for most of the mass of the atom are protons and electrons?
The particles in an atom that account for most of its mass are protons and neutrons, not electrons. Protons, which are positively charged, and neutrons, which have no charge, reside in the nucleus and contribute significantly to the atomic mass. Electrons are much lighter and orbit the nucleus, but their mass is negligible compared to that of protons and neutrons. Thus, the majority of an atom's mass comes from the nucleus.
What electrons are the reactive particles of the atoms?
The Outermost Electrons are the reactive particles of the atoms.
Most alpha particles passed directly through the gold atoms undisturbed what does this evidence suggest about the structure of the gold atoms?
The fact that most alpha particles passed directly through the gold atoms suggests that the majority of an atom's mass is concentrated in a small, dense nucleus. This implies that the rest of the atom consists of mostly empty space with electrons moving around the nucleus.
What is true of an atoms's nucleus?
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
The central core of an atom that contains most of the atoms mass?
The central core of an atom is called the nucleus. It contains protons and neutrons, which account for most of the atom's mass. Electrons orbit around the nucleus in specific energy levels.
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
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.
What are the particles in the atom that account for most of the mass of the atom are protons and electrons?
The particles in an atom that account for most of its mass are protons and neutrons, not electrons. Protons, which are positively charged, and neutrons, which have no charge, reside in the nucleus and contribute significantly to the atomic mass. Electrons are much lighter and orbit the nucleus, but their mass is negligible compared to that of protons and neutrons. Thus, the majority of an atom's mass comes from the nucleus.
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.
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.
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 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.
