Only in exceptional cases: hydrogen, helium, an isotope of lithium which accounts for 8% of lithium on earth, and an isotope of boron (20%).
not usually, a standard atom will contain the same amount of electrons and PROTONS, not neutrons
To maintain the neutrality of an atom the number of neutrons must be equal to number of electrons; in ions this number is not equal.
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.
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.
For a neutral atom, the number of protons (which determines the element) must be equal to the number of electrons. This means that the number of protons should be equal to the number of electrons for the atom to be neutral. Neutrons have no charge, so the number of neutrons does not affect the overall charge of the atom.
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
In an atom, the number of protons is equal to the number of electrons, resulting in a neutral charge. Additionally, in a neutral atom, the atomic number (number of protons) is equal to the number of electrons. However, the number of neutrons can vary among isotopes, so neutrons and protons are not necessarily equal.
No - in fact it is quite rare
An atom of oxygen has 8 protons, 8 neutrons, and 8 electrons. The number of protons determines the element's identity and is equal to the atomic number, while the number of neutrons can vary, leading to different isotopes. The number of electrons is equal to the number of protons in a neutral atom.
No. For an atom to be neutral (no charge, not an ion) the number of electrons must equal the number of protons. Usually the number of electrons is very close to the number of protons though.
The number of protons in an atom is equal to its atomic number, which identifies the element. Neutrons are found by subtracting the atomic number from the mass number. For a neutral atom, the number of electrons is equal to the number of protons.
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
