what is the total electron content of the species Mg2+ and O2- ? Nme 5 more such speceis.
Answers
Answer:
Mg²⁺ = 10 electrons
O²⁻ = 10 electrons
Other elements with 10 electrons: N³⁻, F⁻, Ne, Na⁺, Al ³⁺
Explanation:
The elements and ions that have the same number of electrons are known as isoelectronic species
The ions that are formed by removing electrons are known as cations. They are positively charged
The ions that are formed by gaining electrons are known as anions. They are negatively charged
The electronic configurations of the above elements and ions are given below
N = 1s² 2s²2p³
N³⁻ = 1s² 2s²2p⁶
O = 1s² 2s²2p⁴
O²⁻ = 1s² 2s²2p⁶
F = 1s² 2s²2p⁵
F⁻ = 1s² 2s²2p⁶
Ne= 1s² 2s²2p⁶
Na = 1s² 2s²2p⁶ 3s¹
Na⁺ = 1s² 2s²2p⁶
Mg = 1s² 2s²2p⁶ 3s²
Mg²⁺ = 1s² 2s²2p⁶
Al = 1s² 2s²2p⁶ 3s²3p¹
Al³⁺ = 1s² 2s²2p⁶
Please ignore the explanation if you haven't learnt in this method. I explained this according to the way I have learnt.
Hope it helps you in some way
Answer:
The electronic configurations of the above elements and ions are given below
N=1s² 2s²2p³
N³-=1s²2s²2pº
O=1s² 2s²2p4
0²-=1s²2s²2p
F = 1s² 2s²2p5
F-=1s² 2s²2p
Ne=1s² 2s²2pº
Na 1s² 2s²2p 3s¹
=
Na+ = 1s² 2s²2p⁰
Mg = 1s² 2s²2p 3s²
Mg²+ = 1s² 2s²2pº
Al = 1s² 2s²2p 3s²3p¹
Al³+ = 1s² 2s²2pº
