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.
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
Neutrons have no charge. When the number of protons of an atom is equal to the number of electrons in it, the atom is neutral, in other words, it has no charge.
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.
No - in fact it is quite rare
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.
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.
To have an equal number of protons and electrons, it has nothing to do with the number of neutrons!
The number of electrons should equal the number of protons, otherwise you have an ion.
False. An atom is neutral if it has an equal number of protons and neutrons
The atomic number corresponds to the number of protons in the nucleus of an atom. It also corresponds to the number of electrons in a neutral atom. A neutral atom, you'll recall, is one where the number of electrons equals the number of protons in the nucleus of an atom. We remember that atoms often "loan out" or "borrow" electrons, so the electron count will not always equal the proton count.
