Mn-56
Sulfur-25 has 16 protons and 9 neutrons. Since the element is electrically neutral, it also has 16 electrons.
Manganese has 25 protons, 25 electrons and 30 neutrons.
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
A neutral atom of sodium has 11 electrons. Sodium-25 refers to the isotope of sodium with 25 total protons and neutrons, so a neutral sodium-25 atom would still have 11 electrons to balance the 11 protons in the nucleus.
Manganese (the natural isotope 55Mn) has 25 protons and 30 neutrons.
The symbol Mn indicates a manganese atom, which always has 25 protons. The electroneutrality required for any atom requires the presence of 25 electrons to balance the electrical charge of the 25 protons. The mass number, 52 in this instances, is the sum of the numbers of protons and neutrons. Therefore, the number of neutrons in the isotope is 52 - 25 or 27.
The isotope sulfur-25 doesn't exist.
Sulfur-25 has 16 protons and 9 neutrons. Since the element is electrically neutral, it also has 16 electrons.
Protons: 21 Neutrons: 29 Electrons: Normally 21
Manganese (Mn) has an atomic number of 25, which means it has 25 protons and, in a neutral atom, 25 electrons. The most common isotope of manganese has a mass number of 55, which means it has 30 neutrons (55 - 25 = 30). Therefore, a neutral manganese atom contains 25 protons, 30 neutrons, and 25 electrons.
Manganese has 25 protons, 25 electrons and 30 neutrons.
The isotope 25Na has 11 protons and electrons and 14 neutrons.
The mass number of an isotope is the sum of its protons and neutrons. In this case, the isotope of chlorine has 25 protons and 17 neutrons. Therefore, the mass number is 25 + 17 = 42. Thus, the mass number of this isotope of chlorine is 42.
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
Manganese has 25 protons, 25 electrons and 30 neutrons.
Manganese has 25 protons and electrons and 30 neutrons.
A neutral atom of sodium has 11 electrons. Sodium-25 refers to the isotope of sodium with 25 total protons and neutrons, so a neutral sodium-25 atom would still have 11 electrons to balance the 11 protons in the nucleus.
