It is Iron, Fe.
You think probable to the isotope iron-56.
Manganese is a metal element. Atomic mass number of it is 55.
The element comes with 30 neutrons is iron. It also has 26 protons.
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
The transition metal with 51 neutrons is the element cobalt, which has an atomic number of 27.
The only alkaline earth metal that has a stable isotope with 20 neutrons is calcium.
30 neutrons for Na35Cl and 32 neutrons for Na37Cl .
Lithium: It has 4 neutrons and 3 protons.
Zinc has 30 electrons, 30 protons and 34 neutrons.
Zinc typically has 30 neutrons, as its atomic number is 30 and its atomic mass is around 65.38 g/mol.
Manganese (the natural isotope 55Mn) has 25 protons and 30 neutrons.
Oxygen is a non-metal that has 16 neutrons in its nucleus. It is commonly found in the solid state as part of various compounds like water and minerals.
