3 protons + 4 neutrons = 7
However this is an ion with a +1 charge, but that doesn't affect mass.
9 protons and 10 neutrons in F-19 isotope.
The number of protons
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.
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.
False. The atom that has the same number of protons as it has electrons is a neutral atom.
9 protons and 10 neutrons in F-19 isotope.
Neutrons = 10. Protons = 10. And electrons = 10.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
The number of protons
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
not usually, a standard atom will contain the same amount of electrons and PROTONS, not neutrons
protons-35 neutrons-45 electrons-35
The mass number of this atom is 23, the sum of the number of protons and neutrons.

The protons is 7, the neutrons is 8, and the electrons is 22.
