What is the mass number for a sulfur atom that contains 25 neutrons?
41 = 25 + 16, the latter being the atomic number of sulfur.
What element has 25 protons 25 electrons and a mass number of 56?
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
An atom has a mass number of 25 and 13 neutrons What is the atomic number of this atom?
The element with atomic number 25 is manganese. It has known isotopes with mass numbers including every integer from 49 to 60 inclusive, along with 62. However, the only one that is naturally occurring is the one with mass number 55.
What is the sum of protons and neutrons in an atom?
Mass number!:)
What is the mass number of the atom of argon?
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.

12
What is the mass number for a sulfur atom that contains 25 neutrons?
41 = 25 + 16, the latter being the atomic number of sulfur.
What is the valency of an atom of a mass number 25?
The only non-radioactive isotope with a mass number of 25 is magnesium-25. The valency of magnesium is 2.
If an atom has a number of 25 and an atomic mass of 55?
It is an atom of the element manganese (symbol - Mn).
An atom that contains 15 protons and 10 neutrons within its nucleus will have an atomic mass of?
The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
What element has 25 protons 25 electrons and a mass number of 56?
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.

What do you get when you change the mass number of an atom?
You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number I hope this helped :)
Atomic mass of an atom is called?
What do you mean? Atomic mass of an atom is the weighted average mass of all the naturally occurring isotopes of that element, measured in amu (=atomic mass unit). I do not know how do you want to call it, it is just atomic mass, average atomic mass, mass of an atom, atom's mass...
What is the sum of protons and neutrons in an atom?
Mass number!:)
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
The atomic number of an element is 25 The mass number of one of its isotopes is 58 How many neutrons are in an atom of this isotope?
One can ignore the scant contribution of electrons to atomic mass. Simply add the number of protons and neutrons to obtain 53. Please see the link.
