Atomic number - is the number of protons in the nucleus, which with a neutral atom is also the number of electrons.
In a Periodic Table the elements have the atomic number on them.

Manganese. Im guessing someone didn't do there Santa Susana Homework?
lol.
I have this same assignment
Check the periodic table!
It's Manganese.
Manganese (Mn)
This is the isotope manganese-51.
This chemical element is manganese.

Manganese, the 25th element, has 25 protons.
Manganese has 25 protons, 25 electrons and 30 neutrons.
Manganese (the natural isotope 55Mn) has 25 protons and 30 neutrons.
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
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.
Manganese, the 25th element, has 25 protons.
Chromium's atomic number is 24. Thus it has 24 protons in its nucleus. Manganese is the element with 25 protons.
Manganese (the natural isotope 55Mn) has 25 protons and 30 neutrons.
Manganese has 25 protons, 25 electrons and 30 neutrons.
The isotope 56Mn has 25 protons, 25 electrons, 31 neutrons and a mass number of 56.
Manganese is an element made up of 25 protons and 25 electrons.
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.
Manganese has an atomic number of 25. thus it has, (in its elemental form) 25 protons and 25 electrons.
Protons are protons, no matter what element they are in.
nucleons equal for protons and neutron total. so it should be 25 neucleons.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
Yes, 25 protons and 30 neutrons form the nucleus of Manganese's most stable isotope.
