The number of electrons in an atom is always equal to the number of protons in that same atom. Since the Atomic Mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
The number used to determine how many electrons are in a neutral atom is the atomic number, which is the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is equal to the number of protons, thus balancing out the positive charge of the protons with the negative charge of the electrons.
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.
In a neutral atom of 243Am (Americium), there are 95 protons (which corresponds to its atomic number), approximately 148 neutrons (which can be calculated by subtracting the atomic number from the atomic mass), and 95 electrons (equal to the number of protons in a neutral atom).
7 protons , 8 neutrons and 7 electrons in the neutral atom. Nitrogen has an atomic number of 7. The atomic number is the number of protons in the nucleus. In the neutral atom this is also the number of electrons . The "15" in nitrogen-15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen-15.
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
False. The atom that has the same number of protons as it has electrons is a neutral atom.

no. an atom is made up of protons neutrons and electrons. protons have a charge of plus one electrons have a charge of minus one neutrons have no charge. therefore the number of protons and electrons must be equal (balancing the charges) for the atom to be neutral. ;)

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.
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
