That's Manganese and it has (about) 30 neutrons - - - - BUT your question would have an answer of 11.

∙ 8y agoIf the atomic number is 25, that defines the element as manganese (Mn) and tells you it has 25 protons in the nucleus. The Atomic Mass is equal to the atomic number + the number of neutrons. So, the number of neutrons in the nucleus would be 36-25 = 11. Thus, there are 25 protons and 26 neutrons in the nucleus.

∙ 7y agoThe answer would be 11, if such an atom existed. 11 neutrons is not NEARLY enough to stabilize the nucleus. The manganese nuclide with the fewest neutrons I can find any data on has a half-life of less than 105 nanoseconds, and it's got nearly twice as many neutrons as your hypothetical example.
Manganese has exactly one stable nuclide: Mn-55, which has thirty neutrons.

∙ 8y agoThat atomic mass of 36 represents the total number of protons and neutrons. Atomic number is automatically the number of protons. So, neutrons = 36-25=11.

What does the atomic number tell you about the atomic structure of any element?
An atom contains Protons, Neutrons and Electrons the atomic number is the protons and neutrons combined, the number of protons in the atom is equal to the total number of electrons in the atom which are aranged in the outer shells at 2,8,8,8,8 and so on to find the totoal number of protons in the neucleus of the atom you take the atomic mass and minus the atomic number from it. so He or Helium is 4.0026 atomic mass and 2 for atomic number and so has 2 protons and so in turn has 2 electrons.
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
What is inside the nucleus of an atom?
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged. Physicists believe that there is a cluster of Protons and Neutrons within an Atom's nucleus. Friend Premier is quite right. So instead saying inside the nucleus it would be apt to say that nucleus is made up of...
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
Center of atom?
The center of an atom is the atomic nucleus.
Is atomic mass the amount of neutrons in the nucleus in the atom?
atomic mass = number of neutrons + number of protons.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
What are the differences between the atomic number and the mass number of an atom?
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
Mass number - atomic number?
This is the sum of all protons and neutrons in an atom. On the periodic table, it has the average for that element.
Nucleus of an atom characteristics?
Characteristic for an atomic nucleus are the number of protons and neutrons. Tha atomic nucleus is always positive.
Is the atomic number of an atom is equal to the number of protons or neutrons in the nucleus?
Protons
What does the atomic number of an atom made of?
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What is the difference of atomic number and atomic mass?
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
How is an atomic number similar to mass number?
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
What information does the mass number give?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What does the atomic mass tell you?
It tells you the average amount of protons and neutrons within the nucleus of an atom. In other words, atomic mass - atomic number (protons)= the number of neutrons within the nucleus.
