No. However, about one hundred years ago, before neutrons were discovered, it was considered that atomic nuclei contained electrons to balance the positive charges of part of the protons, since every isotope except hydrogen-1 has a mass number higher than its atomic number, and no neutral subatomic particle was known.
What else can I help you with?
What is true about the atomic nuclei?
The atomic nucleus contain protons and neutrons.
How do you know if 2 nuclei contain the same element?
Two nuclei contain the same element if they have the same number of protons in their atomic structure, which is defined by the atomic number. This number determines the element's identity, regardless of the number of neutrons or electrons. For example, both carbon-12 and carbon-14 are isotopes of carbon, as they both have six protons but differ in their neutron count. Thus, by comparing the atomic numbers of the nuclei, you can determine if they are the same element.
Why is the number of electrons more than nucleus in the sea of electrons model?
In any neutral object the number of electrons is equal to the number of protons. All metallic elements contain more than one proton in the nucleus. Therefore there will be more electrons than atomic nuclei.
How does electron differ from a neutro?
An electron bears a negative charge, a neutron has no charge.A neutron is about 2,000 times as massive as an electron.Neutrons exist in atomic nuclei, electrons orbit nuclei.
What part of an atom determines its size?
the distance from its nuclei and the atomic radius
Which of these statements is true of atomic nuclei.they are very dense.. they contain electrons..they are mostly empty space..they have a neutral charge?
Atomic nuclei are very dense, as they contain protons and neutrons tightly packed together. They do not contain electrons, as electrons orbit around the nucleus. Although nuclei are very small in comparison to the overall size of an atom, they are not mostly empty space. Nuclei typically have a positive charge due to the presence of protons.
Do atomic nucleus contain molecules?
No, atomic nuclei do not contain molecules. Nuclei consist of protons and neutrons bound together by strong nuclear forces, while molecules are formed by the bonding of atoms through shared electrons in their outer shells.
Are there neutrons in a white dwarf?
Yes. A white dwarf is made mostly of electron degenerate matter, which consists of atomic nuclei surrounded by free electrons. The nuclei contain protons and neutrons.
What is true about the atomic nuclei?
The atomic nucleus contain protons and neutrons.
What determines the amount of energy an electrons has?
distance from the atomic nuclei

Do a atomic nucleus contain electrons?
No.
Are Electrons bound to atomic nuclei by strong forces?
False. Electromagnetic force.
What is made of protons and neutrons but not electrons?
Atomic nuclei (and alpha particales, but these are exactly the same as Helium nuclei)
Why are electrons held into the nucleus?
The atomic nucleus doesn't contain electrons.
Why is the number of electrons more than nucleus in the sea of electrons model?
In any neutral object the number of electrons is equal to the number of protons. All metallic elements contain more than one proton in the nucleus. Therefore there will be more electrons than atomic nuclei.
What is the number of electrons that an atomic orbital can contain?
