What element have 25 protons and 30 neutrons?
Manganese (the natural isotope 55Mn) has 25 protons and 30 neutrons.
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.
Atom of a particular element has a unique and characteristic number of these particles?
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
Protons element 25?
Manganese, the 25th element, has 25 protons.
Does chromium have 25 protons in its nucleus?
Chromium's atomic number is 24. Thus it has 24 protons in its nucleus. Manganese is the element with 25 protons.
What element have 25 protons and 30 neutrons?
Manganese (the natural isotope 55Mn) has 25 protons and 30 neutrons.
How many protons neutrons and electrons are in the element manganese?
Manganese has 25 protons, 25 electrons and 30 neutrons.
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 is maganese made for?
Manganese is an element made up of 25 protons and 25 electrons.
How many electrons are in Magnesium-25?
Magnesium has an atomic number of 12, so there are 12 protons in any atom of this element. The number of protons do not change if it is an isotope of an element.
What element has the closest number to 25 electrons?
Manganese has an atomic number of 25. thus it has, (in its elemental form) 25 protons and 25 electrons.
What is the name of protons in the atoms of an element?
Protons are protons, no matter what element they are in.
What element has 12 protons 13 neutrons and 15 nucleons?
nucleons equal for protons and neutron total. so it should be 25 neucleons.
How many protons are in an atom of a pure element?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
Are the protons and neutrons attached to the nucleus of the manganese element?
Yes, 25 protons and 30 neutrons form the nucleus of Manganese's most stable isotope.
