What has the smaller mass protons electrons or nutrons?
Electrons have the smallest mass compared to protons and neutrons. The mass of a proton is approximately 1836 times greater than the mass of an electron, and the mass of a neutron is slightly greater than that of a proton.
Where can most of the mass in an atom be found?
Most of the mass in an atom can be found in the nucleus, which houses the protons and neutrons. Protons and neutrons are much more massive than electrons, which orbit the nucleus in the electron cloud.
Do all atoms weight the same?
No, not all atoms weigh the same. The weight of an atom is determined by the combined mass of its protons, neutrons, and electrons. Different elements have different numbers of protons, neutrons, and electrons, leading to variations in atomic weight.
How are electrons neutrons and protons different?
Protons have a positive (+) charge.Neutrons have no charge.Electrons have a negative (-) charge.Proton and neutron are roughly the same sizeElectrons are considerably smaller than protons or neutronsProtons and neutrons have a relative atomic mass of 1The mass of electrons is so small it is not included in calculations of an atom's mass.
What is the difference between a proton electron and a nuetron?
Electrons have virtually no mass, are negatively electrically charged and are to be found orbiting an atoms nucleus in what are called electron shells. Protons and Neutrons are to be found the the atoms nucleus and they have mass. Neutrons have no electrical charge while Protons are positively charged. For every Proton to be found in an atom's nucleus, there is a matching electron in one of the electron shells so that overall the + and - electrical charges balance out. The number of protons in the nucleus of an atom determines what element that atom makes. Neutrons stabilize the atom's nucleolus by separating the + charge protons and their number may vary in an atom - a variation in the number of neutrons in the nucleus with a given number of protons gives rise to atomic isotopes. Neutrons also have no charge. Protons and Neutrons are located in the nucleus. Protons=Positive. Neutrons=no charge. Electron=E-=Negatively charge.
Do protons electons and neutrons differ in mass?
As I remember neutrons and protons weight something similar, electrons have a far smaller mass which is negligable in comparison to the weight of protons.
What particles make up the mass of an atom?
The number of protons
What particle control the 'weight' of an atom?
The weight of an atom is primarily controlled by the total number of protons and neutrons in its nucleus. Protons and neutrons have approximately the same weight, while electrons have negligible mass compared to protons and neutrons.
The atomic mass is determined by the weight of?
The number of protons, neutrons and 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.
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
Atomic mass represents the weight of an atoms protons neutrons and electrons however the atomic mass is generally used to refer to just the number of protons and neutrons why?
its not D
What determines the mas of an atom?
The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
How do you find the mass of electrons?
Nuclear Physicists don't really count electrons to have weight. An atom's mass comes from protons and neutrons.
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
Atomic mass of an atom is determined by the combined masses of?
Atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, as they are much heavier than electrons. The atomic mass is usually given in atomic mass units, where 1 unit is defined as 1/12 the mass of a carbon-12 atom.
The atomic mass of an element is determined by its total number of?
protons and neutrons in the nucleus. It is calculated by adding the number of protons and neutrons in an atom. Electrons do not significantly contribute to the atomic mass due to their much smaller mass compared to protons and neutrons.
