Question

What is the electron structure of a beryllium ion with a net ionic charge of +2?

1s1
1s2
2s1
2s2

Answer 1

Im pretty sure its 1s2

Answer 2

Answer: The electron structure of
`Be^(2+)` ion is
`1s^2`

Step-by-step explanation: Beryllium is the 4th element of the periodic table.

The electronic configuration of Be-element in its ground state is:

`Be(Z=4):1s^22s^2`

For the Beryllium element to have +2 charge, two electrons must be removed from the electronic configuration. So, the electronic configuration for the
`Be^(2+)` ion is:

`Be^(2+):1s^2`
