In the following table, all the columns for the element oxygen are filled out correctly. Element Electron Structure of Atom Electron Structure of Ion Net Ionic Charge Oxygen 1s2, 2s2, 2p4 1s2, 2s2, 2p6 -2 True False

1s², 2s², 2p⁴

Explanation:

Hello,

To determine the filling of electrons in an orbital, we'll have to apply several rules such as

1. Aufbau principle

2. Hunds rule

3. Pauli's exclusion principle.

I won't explain the above rules because I don't want to deviate from the question, but however if you understand them, it'll make questions like this easier to answer.

For oxygen atom

₈O = 1s² 2s² 2p⁴

The filling of the orbital must start with 1s orbital till the space of the two electrons are filled before moving to 2s orbital filling the two space in the shell and then finally the remaining 4 electrons on the 2p orbital.

Assuming the net ionic charge of oxygen in this case is zero (0) and has not accepted electron.

However, oxygen usually accepts 2e⁻(electrons) to attain stability (all orbital strive to attain duplet or octet configuration).

Assuming we have O²⁻, the electron configuration change to 1s² 2s² 2p⁶. This is the state oxygen usually forms compounds in excerpts with group 1 metals where it is able to form super oxide.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
