How many protons are in manganese?

Answer 1

Many atoms have many different isotopes, and each isotope has a different number of neutrons. Mn only has 1 stable isotope, which is 55 Atomic Mass. It is atomic number 25 and thus has 30 neutrons.

Answer 2

Manganese, like all other elements, has a number of different isotopes. The different isotopes of any given element have the same number of protons (which gives an atom its elemental identity), but can have different numbers of neutrons in them. The only stable isotope of manganese is 55Mn, and it has 30 neutrons. The other 3 isotopes that are most notable are 52Mn, 53Mn and 54Mn, and they have 27, 28 and 29 neutrons, respectively. Other isotopes have been synthesized, and they have neutron counts from 19 through 44. The link below is to the Wikipedia article on manganese. The aforementioned isotopes are mentioned in this article, and a link is provided to permit the curious investigator to see what other isotopes have been discovered.

Answer 3

The element manganese has 25 protons in its nucleus. You'll recall that the number of protons in an atom gives it its chemical identity, and only that. It will also have 25 electrons when the atom is in the neutral state. (Manganese normally "loans out" electrons in chemical reactions.) There are 30 neutrons in the only stable isotope of manganese, but there are a number of different isotopes of this transition metal. They've been synthesized, of course, and the number of neutrons ranges from 19 through 44. A link can be found below.

Answer 4

Manganese is element number 25 (atomic number) and has 25 protons. Isotope of Mn with atomic mass number 55 has thus 55-25 = 30 neutrons. Mn-54 has one neutron less. These are all exact, not approximate, numbers.

The atomic weight of Manganese is approximately 54.93805 a.m.u.

Answer 5

25Mn-55 (the naturally occurring isotope) has 25 protons, 25 electrons and 30 neutrons,

25Mn-54 has 29 neutrons instead but is not a stable isotope.

Answer 6

In the nucleus of manganese there are 25 protons because the number of protons is the same as its atomic number which is 25.

Answer 7

Twelve protons in Mg

Answer 8

Manganese has 25 protons.

Answer 9

30
