Question

answer each question about the following atom when it becomes an ion. oxygen determine the ionic name. ion write the chemical symbol and charge. the ionic charge of is achieved when the atom electrons.

Explanation:

Step1: Recall oxygen's electron - gaining behavior

Oxygen is in group 16 of the periodic table and has 6 valence electrons. It gains 2 electrons to achieve a stable octet.

Step2: Determine the ionic name

When oxygen gains 2 electrons, it forms an anion. The ionic name is oxide ion.

Step3: Write the chemical symbol and charge

The chemical symbol for oxygen is O. Since it gains 2 electrons, the charge is 2-. So the symbol is $O^{2 - }$.

Step4: Explain the ionic charge

The ionic charge of 2 - is achieved when the oxygen atom gains 2 electrons.

Answer:

1. Oxide
2. $O$, 2 -
3. 2 -, gains, 2
