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.

How make a strontium atom for a science project?
You can create a model of a strontium atom by using different colored pom poms to represent protons, neutrons, and electrons. The nucleus can be represented by a larger pom pom with smaller pom poms surrounding it to depict electrons in different energy levels. You can also use toothpicks or pipe cleaners to show the arrangement of the electrons in their orbits around the nucleus.
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 is the atom of uranium bigger?
The atom of uranium is larger than other atoms because it has more protons, neutrons, and electrons. Uranium has a higher atomic number, meaning it has more protons in its nucleus compared to smaller atoms. The additional protons and neutrons in the nucleus lead to a larger atomic size overall. Additionally, the electron cloud surrounding the nucleus is also more spread out in uranium atoms due to the increased number of electrons, contributing to its larger size.
Which is more dense the nucleus or the electron cloud?
The nucleus is significantly more dense than the electron cloud. The nucleus contains most of the mass of an atom, while the electron cloud occupies a much larger volume with a very low density.
Why does the electron cloud become larger as the value of n increases?
The electron cloud becomes larger as the value of n increases because electrons in higher energy levels are on average farther from the nucleus. These higher energy levels have more sublevels and orbitals, resulting in a larger spatial distribution of the electron cloud. This increased distance from the nucleus leads to a larger orbital size.
Electrons shared in a molecule are held where to the atoms with the larger nucleus?
Electrons shared in a molecule are held closer to the atom with the larger nucleus due to its greater positive charge, which exerts a stronger attractive force on the negatively charged electrons. This results in the electron density being unequally distributed in the molecule, creating a partial negative charge near 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.
Is electrons are the largest particles in an atoms?
An electron is not the largest part of an atom. An electron is the smallest component of an atom. Relatively, if a neutron or proton were 1 unit in size, an electron would be 1/1840 units in size.

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 is the difference between protons and electrons?
A proton is positive and an electron is negative Protons are approximately 1,835 times the mass of the electron. Protons are in the nucleus. Electrons are in the 'shells'.
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.
Which has lower ionization energy an atom with a small radius or an atom with a large radius?
An atom with a larger radius typically has lower ionization energy. This is because in larger atoms, the outermost electrons are farther from the nucleus and experience weaker attraction, making it easier to remove them compared to smaller atoms where the electrons are closer to the nucleus and held more tightly.
Why the size of atom is biggest than nucleus?
The size of an atom is bigger than the nucleus because an atom consists of a nucleus surrounded by electron clouds. The electrons are located further away from the nucleus, leading to the overall larger size of the atom.
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.
Why is the atom of uranium bigger?
