What else can I help you with?
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
How many electrons are in its outer energy level for Magnesium?
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
Which electrons in a magnesium atom are most likely to be lost?
The outermost electrons, found in the highest energy level, are the most likely to be lost in a magnesium atom. Magnesium has 2 electrons in its outermost energy level, so it tends to lose these electrons to achieve a stable electron configuration.
What is a valence shell of mg?
The valence shell of magnesium (Mg) contains 2 electrons in the outermost energy level. This is because magnesium is an alkaline earth metal with 2 valence electrons. These electrons are located in the 3s orbital in the third energy level.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
How many electrons are in the third energy of a magnesium atom?
If you are talking about the electronic structure, which is 2.8.2. This would therefore mean that there are 2 electrons in the outer shell of magnesium.
How many valence electrons does magne sium have?
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence 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.
Does helium has the same amount of electrons in its outer shell as magnesium?
No, helium has 2 electrons in its outer shell, while magnesium has 2 electrons in its outer shell. So, they do not have the same amount of electrons in their outer shell.
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 are in the outer shell of a typical magnesium atom?
A typical magnesium atom has 2 electrons in its outer shell. Magnesium is in Group 2 of the periodic table, so it has 2 electrons in its outermost 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.
