Question

Predict any four different atoms or ions with electronic configuration 2,8​

Answer 1

Answer:

hi friend, mark me brainliest for further help and support

Explanation:

for different atoms with their starting electronic configuration to be 2,8 are:-

=> calcium, scandium, uranium,nickel,copper etc. (yo you can give any eg after calcium for this)

for different IONs with their starting electronic configuration to be 2,8 are:-

magnesium($Mg^+2$) , calcium(Ca+2) , copper(Cu+2), Iron(fe+2) etc...

yo friend, remember one thing,that ,

while writing electronic configuration for ions you should first count the no of protons and then subtract the charge to find the no.of electrons
