it is protons and electrons. your welcome and vote this best answer!
The barium atom (neutral) contain 56 electrons.
Protons, neutrons, and electrons are subunits present in equal numbers in an atom. The number of protons in an atom is equal to the number of electrons, while the number of neutrons can vary in different isotopes of an element.
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
In a electrically neutral atom, the number of positive charges in the atom's nucleus (with one charge being held on each proton in the nucleus), is balanced out by the number of negative charges present in the electron cloud round the nucleus (with one charge being held on each electron in the cloud). This means that in a neutral atom the number of Protons = the number of Electrons.
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
The protons and electrons are equal in number in a neutral atom
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
An equal number of protons and electrons.
The numbers of each are equal! Therefore the atom is neutral.
A neutral atom of uranium has 92 electrons. This is because the number of electrons is equal to the number of protons in the nucleus of an atom, and an atom is neutral when the number of electrons is equal to the number of protons. Uranium has an atomic number of 92, which corresponds to the number of protons and electrons in a neutral atom of uranium.
No, if an atom is neutral the number of electrons and protons will be equal. Neutrons have no charge and do not affect the overall charge of the atom.
