Why the density of nucleus is larger than surrounding electrons in an atom?

∙ 11y ago
The lightest nuclei is composed of one proton whose mass is around 1836 times the one electron mass. Any atom is composed of a nucleus (composed of protons and neutrons and the neutron is heavier than the proton) and surrounded by a number of electrons that are equal to the number of protons). So,alwaysthe nucleus is heavier than the mass of the surroundingelectrons.

Why large atoms are more likely to lose electrons?
In simplistic terms, an atom's electrons are held tot he atom because they are attracted to the positively charged nucleus. In larger atoms the electrons are farther away from that nucleus and there are usually more electrons in between, resulting in a weaker attraction.
How do you rank configurations by atomic radius?
Nuclear radius increases as you go down and to the left on the periodic table due to effective nuclear charge. Bassicaly, it means that sheilding of electrons by larger atoms having more things in the way that blocks the ability of the nucleus to pull on the electrons, thus the electrons are able to be further from the nucleus and have a larger radius.
Why compounds of Xe are more common as compared to other noble gases?
Xenon has larger size and hence the valence electrons do not have much attraction with the nucleus. So these electrons are available for bonding with other elements.
Are electrons larger then molecules?
is it true electrons larger then molecules
Is the most of the volume of an atom empty space or nucleus?
Most of the atom is empty space (between the electron orbitals and the nucleus itself). If your talking about nucleus vs. electrons then the nucleus is larger in volume and mass
Electrons shared in a molecule are held where to the atoms with the larger nucleus?
Electrons shared in a molecule are held more closely to the atom with the larger nucleus
What is larger n He atom or an Ne atom?
the sodium atom as it has a larger nucleus and more electrons.
What does the nucleus of copper look like?
The nucleus of copper consist of Protons and Nuetrons. Which make up the bulk of the mass of copper with nuetrons being slightly larger than protons. In the electron cloud surrounding the nucleus commonly depicted as rings are where the electrons are located. In a regular copper atom you will find 29 protons, 29 electrons, and somewhere in between 28-30 nuetrons depending on the isotope.
Is aluminum a better conductor than sodium?
Yes..Aluminium has a larger charge (more electrons) and the electrons cloud are more compress to the nucleus (small atomic radius) compared to Sodium. So the density of Aluminium is larger and this leads to better conductivity of electricity.
Why is sulfur larger than oxygen?
Sulfur is larger than oxygen because it has more protons in its nucleus and more electrons in the orbital shells.
Why large atoms are more likely to lose electrons?
In simplistic terms, an atom's electrons are held tot he atom because they are attracted to the positively charged nucleus. In larger atoms the electrons are farther away from that nucleus and there are usually more electrons in between, resulting in a weaker attraction.
Why will aluminum create an ion larger than its nucleus?
It will become smaller because the three electrons it will lose decreases the size of the 'cloud' of electrons rather than making it larger. They also will be 'held' tighter to the nucleus. The opposite is true of those elements that gain electrons.
How do you rank configurations by atomic radius?
Nuclear radius increases as you go down and to the left on the periodic table due to effective nuclear charge. Bassicaly, it means that sheilding of electrons by larger atoms having more things in the way that blocks the ability of the nucleus to pull on the electrons, thus the electrons are able to be further from the nucleus and have a larger radius.
Why does potassium have a larger atomic radius than bromine?
When looking at potassium and bromine, it would seem that with more electrons occupying more orbitals, bromine would be larger. However, in addition to those additional electrons, bromine also has additional protons. These protons in the nucleus pull on all of bromine's electrons with more strength than the nucleus of potassium, and the stronger pull offsets any size gained by adding electrons. In short, bromine's nucleus pulls harder.
Why does bigger size atom have more shielding effect?
The bigger the atom, the larger the number of electrons between the outermost energy level and the positively charged nucleus. As a result, the attraction between the electrons in the outermost energy level and the nucleus are slightly weaker, and so, the larger the atom, the greater the sheilding effect.
What does the atomic mass tellus about the structure of the atom?
The more massive an atom is, the larger the nucleus and the more electrons are spinning around it.
What is the factor that affects the atomic number in an element?
More shielding of the outer electrons by the inner electrons is the most important factor that affects the atomic number in an element. A valence electron in an atom is attracted to the nucleus of an atom and is repelled by the other electrons in the atom. The inner electrons shield the outer electrons from the attraction of the nucleus and cause the atomic radius to be larger.
