1s2 2s2 2p6
The electron configuration of neon is [He]2s2.2p6.
Mg 2+ Has the same electron configuration as neon. Two electrons lost to do this.
It has the same electron configuration as in a neon atom.
When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.
Their electron configuration =)
1s2 2s2 2p6
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.
1s22s22p6.
The electron configuration of neon is [He]2s2.2p6.
Phosphorus has an electron configuration of 1s2 2s2 2p6 3s2 3p3. Another way to write that is [Ne] 3s2 3p3. The [Ne] represents the fact that the beginning of phosphorus' electron configuration is the same as Neon's.
Mg 2+ Has the same electron configuration as neon. Two electrons lost to do this.
2, 8 is the electron configuration
It has the same electron configuration as in a neon atom.
The inert gas in Period 2 is the element Neon(Ne). Its electron configuration is 2-8.
Helium's electron configuration is 1s2. Neon's electron configuration is 1s22s22p6. All of the rest of the noble gases, like neon, have the maximum number of electrons in their outermost s and p orbitals (valence shells), which is eight.
When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.
