Magnesium (Mg) has atomic number 12, so the electron configuration is
1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
To determine the number of valence electrons in an atom using its electron configuration, look at the highest energy level (n) in the electron configuration. The number of electrons in this energy level is the number of valence electrons.
To determine the number of valence electrons in an atom based on its electron configuration, look at the outermost energy level of the atom. The number of electrons in this energy level is the number of valence electrons.
Valence electrons are the outermost electrons in an atom that are involved in chemical bonding, while electron configuration refers to the arrangement of electrons in an atom's energy levels or shells.

There are 2 electrons in the valence orbital of a Magnesium atom.
Valence electrons are the outermost electrons in an atom that are involved in chemical bonding, while electron configuration refers to the arrangement of electrons in an atom's energy levels or shells.
The magnesium has 2 valence electron while the oxygen misses 2 electron to complete its octet. An atom is always more stable when it has 8 valence electrons. The magnesium will create an ionic bond with the oxygen by giving its 2 electrons to form Magnesium Oxide, MgO.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
A magnesium atom has 12 electrons arranged in 3 shells. The electron configuration of magnesium is 2-8-2, indicating that it has 2 electrons in the first shell, 8 in the second shell, and 2 in the third shell.
Short answer: [Ar] 3d10 4s2 4p3 OR 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3
To determine the number of valence electrons in an electron configuration, look at the outermost energy level of the atom. The number of electrons in this level is the number of valence electrons.
The element is magnesium with the electronic configuration 2, 8, 2 and has 2 valence electrons.
