the proton number of an atom is the same as the neutron number, therefor there is 12 electrons as well as 12 protons.
12 electrons, and probably has 12, 13 or 14 neutrons in its nucleus as well. It's magnesium. Please see the link.
Yes. It's the most common isotope of magnesium.
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
In an atom of gold, there are 79 protons and 79 electrons. The number of neutrons for gold may vary by isotope.
15 protons, 15 electrons and 16 neutrons (for its most stable isotope)
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
Sulfur-32 has 16 protons, neutrons and electrons each.
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
This isotope has 20 protons and and electrons and 22 neutrons.
An atom with 15 protons, 15 neutrons, and 15 electrons.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
In an atom of gold, there are 79 protons and 79 electrons. The number of neutrons for gold may vary by isotope.
9 protons and 10 neutrons in F-19 isotope.
Titanium has 22 protons, 22 electrons and 24-28 neutrons - depending on the isotope.
15 protons, 15 electrons and 16 neutrons (for its most stable isotope)
It contains 104 electrons/protons and 159 neutrons.
Helium isotope
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
