Question

What happens when the compound Mgo is formed? (5 points)

Oxygen transfers two electrons to magnesium.
Oxygen receives two electrons from magnesium.
Magnesium forms an ion with -1 charge; oxygen forms an ion with +1 charge.
Magnesium forms an ion with +1 charge; oxygen forms an ion with -1 charge.

Answer 1

Oxygen receives two electrons from magnesium.

Step-by-step explanation:

Answer 2

Oxygen receives two electrons from magnesium.

Step-by-step explanation:

Hello!

In this case, considering the chemical reaction by which magnesium oxide is produced:

`2Mg+O_2\rightarrow 2MgO`

In that case, if we show up the oxidation states, we have:

`2Mg^0+O_2\rightarrow 2Mg^(2+)O^(2-)`

In such a way, since metals, like magnesium, have the capacity to lose electrons, rather than receive them, we infer why it turns out with +2 rather than -2; thus, we the correct answer is "oxygen receives two electrons from magnesium." because it results with -2 in MgO.

Best regards!
