Atomic magnesium has three shells.
The shell numbering parallels the row number of the first three rows of the Periodic Table.
Magnesium is in the third row. We number these 1,2,3 etc. and because of historical reasons, we also label them as K,L,M ... etc.
Electron configuration of magnesium's shells are as follows.
- 1s2
- 2s2 and 2p6 (one shell, two orbitals: 2s and 2p, of which the last one has 3 sub-orbitals: 2px, 2py, 2pz, each filled with 2 electrons)
- 3s2
With 2 electrons in the first shell, 8 electrons in the second and the last 2 in the 3rd, all 12 electrons of magnesium are accounted for. Done.
Aside: The next row is where it gets tricky, but that is a separate question.
What else can I help you with?
How many electrons will Magnesium lose to have the same electron configuration has Neon?
Magnesium will lose 2 electrons to have the same electron configuration as Neon. Neon has a full valence shell with 8 electrons, and Magnesium has 2 valence electrons. By losing 2 electrons, Magnesium can achieve a full valence shell and the same electron configuration as Neon.
What happens when a magnesium atom loses an electron?
It becomes a positively charged Magnesium ion.
What happens when a magnesium atom loses an election in its outer energy shell?
When a magnesium atom loses an electron in its outer energy shell, it forms a positively charged magnesium ion (Mg2+). This ion has a stable electron configuration similar to that of a noble gas, which makes it more chemically reactive.
How many electrons does Magnesium have in its outer most shell?
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
How many electrons does Magnesium need to complete the last shell?
A magnesium atom would need 6 electrons to complete its highest occupied electron shell. In practice, a magnesium atom almost never does this, because the energy required would be too great. Instead, the magnesium atom transfers 2 electrons to one or more atom that are more electronegative than magnesium and thereby forms a magnesium ion with an electrical charge of +2. In this ion, the highest occupied shell of a magnesium atom is completely empty of electrons.
How many shells does magnesium atom have?
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.
How many electron configurations does magnesium have?
2 Because Magnesium only has 2 electrons in it's outer shell
How many electrons will Magnesium lose to have the same electron configuration has Neon?
Magnesium will lose 2 electrons to have the same electron configuration as Neon. Neon has a full valence shell with 8 electrons, and Magnesium has 2 valence electrons. By losing 2 electrons, Magnesium can achieve a full valence shell and the same electron configuration as Neon.
What happens when a magnesium atom an electron in its energy shell?
When a magnesium atom gains an electron in its energy shell, it becomes negatively charged and transforms into a magnesium anion (Mg²⁻). This process occurs because magnesium has three valence electrons and seeks to achieve a stable electron configuration. Gaining an electron allows it to fill its outer energy shell, but typically, magnesium tends to lose its valence electrons to form a cation (Mg²⁺) instead. Thus, while it is theoretically possible for magnesium to gain an electron, it is more common for it to lose electrons in chemical reactions.
How many electrons does magnesium have in its outermost electron as a result you would expect magnesium to form ions charge of?
Magnesium has 2 electrons in its outermost electron shell. As a result, you would expect magnesium to form ions with a charge of +2 by losing these two outer electrons to achieve a stable electron configuration.
How many electrons are in the outter shell of magnessium?
There are 12 electrons in the electron shell of magnesium, the same number as protons. As for the outermost shell, it would be 3s2, meaning there are two electrons in the third "s" shell.
What happens when a magnesium atom loses an electron?
It becomes a positively charged Magnesium ion.
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.
What happens when a magnesium atom loses an election in its outer energy shell?
When a magnesium atom loses an electron in its outer energy shell, it forms a positively charged magnesium ion (Mg2+). This ion has a stable electron configuration similar to that of a noble gas, which makes it more chemically reactive.
Magnesium has an atomic number 12 and an atomic mass number 24 how many electrons are in its third energy shell?
Magnesium has 12 protons and electrons and its electronic configuration is 2.8.2, therefor it has 2 electrons in its 3rd energy level or elcectron outer shell
What happens when a magnesium arom loses an electron in its outer energy shell?
When a magnesium atom loses an electron from its outer energy shell, it becomes a positively charged ion known as a magnesium ion (Mg²⁺). This process occurs because magnesium has two electrons in its outer shell, which it tends to lose to achieve a stable electron configuration similar to that of noble gases. The loss of this electron allows magnesium to participate in ionic bonding, typically forming compounds with nonmetals. Consequently, the atom's overall charge changes from neutral to positive due to the imbalance between protons and electrons.
What happens when a magnesium atom loses an electron in its outer engery shell?
When a magnesium atom loses an electron from its outer energy shell, it becomes a positively charged ion, specifically a magnesium ion (Mg²⁺). This loss occurs because magnesium has two electrons in its outer shell, which it tends to lose to achieve a stable electron configuration similar to that of noble gases. As a result, the atom's reactivity increases, and it can readily bond with other elements to form compounds.
