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.

∙ 11y agoi think atoms contain electrons. they have protons and neutrons too.
-ap chemistry badass. i have a B-
Wiki User
∙ 15y agoIn their natural state, yes, however the hydrogen ion is simply a lone proton with no neutrons or electrons.
Wiki User
∙ 14y agoYes, even hydrogen, it's just not a very big cloud.
Wiki User
∙ 12y agoNope, Nucleus of an atom contains only protons and neutrons. Electrons are around the nucleus.
Wiki User
∙ 11y agoYes. every atom has atleast one electron and proton
Wiki User
∙ 11y agoNo. The nucleus of an atom has neutrons and protons. The electrons are revolving around the nucleus of an atom.
Wiki User
∙ 11y agoYeah, they do.

What is true about the atomic nuclei?
The atomic nucleus contain protons and neutrons.
Do the alpha particles in Rutherford's experiment contain electrons?
Alpha particles are helium-4 nuclei; they do not 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.
If fluorine has an atomic number of 9 and an atomic mass of 19 how many electrons does fluorine contain?
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
A structure in which atomic symbols represent nuclei and inner-shell electrons and in which dots are used to represent valence electrons are called?
lewis dot
What determines the amount of energy an electrons has?
distance from the atomic nuclei
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 a mixture of sub atomic particles nuclei and electrons?
An ATOM. The sub-atomic particles are Protons, Neutrons. and Electrons. The protons and neutrons are collectively named 'nucleons, because they form the nucleus of an atom. The electrons are in energy shells around the nucleus.
What is made of protons and neutrons but not electrons?
Atomic nuclei (and alpha particales, but these are exactly the same as Helium nuclei)
What is true about the atomic nuclei?
The atomic nucleus contain protons and neutrons.
Do the alpha particles in Rutherford's experiment contain electrons?
Alpha particles are helium-4 nuclei; they do not contain electrons.
Holding electrons in orbit around atomic nuclei is an electric force of what between what and what?
Between protons and electrons.
Do a atomic nucleus contain electrons?
No.
Are Electrons bound to atomic nuclei by strong forces?
False. Electromagnetic force.
Does fluorine contain 10 electrons?
it has 9 electrons atomic number= number of protrons and electrons and atomic mass-atomic number=neutrons
Location of electrons?
Electrons are naturally to be found in shells surrounding atomic nuclei.
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.
