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 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.
What is the electron configuration of an atom with the atomic number of 11?
The electron configuration of an atom with the atomic number of 11 (which corresponds to the element sodium) is 1s2 2s2 2p6 3s1.
What happens to the electron configuration as the atomic number increases?
the elctron configuration increases
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.
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
