It is manganese.

Mg - Magnesium
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
25 electrons.... ( as the number is 25 : being 25 protons and 25 electrons)
nickel has 28 electrons and is in the metal family
The transition metal with 25 electrons that starts with an O is the element named "osmium" (Os). It belongs to the platinum group of metals and has a dense, bluish-white appearance. Osmium is commonly used as an alloying agent in the production of hard and durable materials.
Calcium is a metal that has two valence electrons.
manganese. In the future look at the table of elements with the top number (called the atomic number: which is the number of protons, which also equals the number of electrons,) to see the number of electrons
In a chemical reaction between a metal and a non-metal, electrons are typically transferred from the metal to the non-metal. The metal loses electrons to form cations, while the non-metal gains electrons to form anions. This transfer of electrons results in the formation of an ionic bond between the two elements.
Free electrons in a metal are called conduction electrons. These are loosely bound to the metal lattice and are able to move freely throughout the material, allowing metals to conduct electricity efficiently.
Manganese has 25 electrons. Hope this helps. :)
