Knowing the nuclear charge of an element is important as it will tell you what kind of reactions you can expect. The element with the nuclear charge of 25 is manganese.
41 = 25 + 16, the latter being the atomic number of sulfur.
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
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.
Mass number!:)
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
41 = 25 + 16, the latter being the atomic number of sulfur.
The only non-radioactive isotope with a mass number of 25 is magnesium-25. The valency of magnesium is 2.
It is an atom of the element manganese (symbol - Mn).
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.
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
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.
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 :)
Mass number!:)
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...
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.
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
