What is the valence electron configuration for the magnesium atom?
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
What is the electron configuration of atomic number 26?
The electron configuration of atomic number 26 (iron) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6.
What is the element for 1s22s22p63s2?
Magnesium (Mg) with two valence electrons
What is the electron configuration of an atom with the atomic number 10?
The electron configuration of an atom with the atomic number 10 (neon) is 1s2 2s2 2p6.
Magnesium atomic number 12 forms a magnesium ion that may be represented as?
Magnesium ion (Mg2+) has a 2+ charge, meaning it has lost two electrons to achieve a stable electron configuration similar to a noble gas. It forms when magnesium atom (with atomic number 12) loses two electrons.
What is the valence electron configuration for the magnesium atom?
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.

What is the number of electrons in 3s in magnesium?
Magnesium (Mg) has an atomic number of 12, indicating it has 12 electrons. The electron configuration for magnesium is 1s² 2s² 2p⁶ 3s². Therefore, there are 2 electrons in the 3s subshell of magnesium.
What is the element for 1s22s22p63s2?
Magnesium (Mg) with two valence electrons
What is the electron configuration of an atom with the atomic number 10?
The electron configuration of an atom with the atomic number 10 (neon) is 1s2 2s2 2p6.
What i s the configuration for Mg?
The element magnesium (atomic number 12) has the electron configuration of1s2 2s2 2p6, 3s2or the noble gas abbreviation [Ne] 3s2(see related link)The electron configuration for neutral magnesium (Mg) is 1s22s22p63s2. The ion, Mg2+, has two electrons fewer, so the outer two electrons are removed from the electron configuration. This changes the electron configuration to 1s22s22p6, which is the same electron configuration as the noble gas neon.
What element does Ne 3s2 represents?
The notation "Ne 3s2" seems to reference an electron configuration, but it appears to be a bit misleading. Neon (Ne) has the atomic number 10 and its electron configuration is 1s² 2s² 2p⁶. The "3s2" part suggests an electron configuration for a different element, specifically for magnesium (Mg), which has the configuration of 1s² 2s² 2p⁶ 3s² and an atomic number of 12.
Magnesium atomic number 12 forms a magnesium ion that may be represented as?
Magnesium ion (Mg2+) has a 2+ charge, meaning it has lost two electrons to achieve a stable electron configuration similar to a noble gas. It forms when magnesium atom (with atomic number 12) loses two electrons.
What is the valency number of magnesium?
Valency is not a word... but if you want to know the number of valence electrons that Magnesium has, it is 2. Magnesium's atomic number is 12.
What does the sum of the superscript equal in a electron configuration?
The sum of the superscript in an electron configuration is equal to the atomic number.
In the electron configuration what does the sum of the superscripts equal?
The sum of the superscript in an electron configuration is equal to the atomic number.
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
