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?
When a magnesium atom loses an electron, it becomes a positively charged ion called magnesium ion (Mg²⁺). This ion has a full outer electron shell, making it more stable.
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.
Why is potassium bigger then magnesium?
Potassium is larger than magnesium because potassium has one more electron shell than magnesium, leading to a larger atomic size. Additionally, the increase in nuclear charge from magnesium to potassium is not enough to offset the added electron shell, resulting in a larger atomic radius for potassium.
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.
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?
When a magnesium atom loses an electron, it becomes a positively charged ion called magnesium ion (Mg²⁺). This ion has a full outer electron shell, making it more stable.
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 electrons, so its electron configuration is 2-8-2. In its third energy shell, there are 2 electrons.
What happens when a magnesium ion loses an electron?
When a magnesium ion loses an electron, it forms a magnesium ion with a 2+ charge. This occurs because magnesium typically has 2 electrons in its outer shell, and losing one electron leaves it with a full outer shell, resulting in greater stability.
How many outer shells are there in magnesium?
Magnesium has 3 outer electron shells. It has 12 electrons with 2 in the first shell, 8 in the second shell, and 2 in the third shell.
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.
