Assuming we're dealing with a neutral atom, you're thinking of manganese (Mn). It has 25 protons and is a transition metal in period 4, group 7B on the Periodic Table.
Molybdenum is the element that has 42 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.
In the electronic configuration when the last shell is filled with 1,2 or 3 electrons then the element tends to give out electrons. when elements give out these 1,2 or 3 electrons it becomes positive these positive atoms are metals
the valence electrons cause the chemical reations. the valence electrons decide that element attract to which element.
A transition element of f-block Thorium has 90 electrons in natural state, it is a Radioactive element.
Mg - Magnesium
The element with Atomic number 30 is "Zn" Zinc.
Manganese
Manganese
Manganese, Mn is a transition element with Atomic number 25 and thus 25 electrons.
Manganese has an atomic number of 25. thus it has, (in its elemental form) 25 protons and 25 electrons.
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.
Manganese is the 25 element in the Periodic Table of the elements, therefore it has 25 electrons, this is the number of electrons in each shell: 2, 8, 13, 2.
In a stable, Neutral system, the protons and electrons will be equal. The element with atomic number 25 is Manganese (Mn), See the periodic table
silver, copper, tin, and mercury is used also know as amalgam.
