Magnesium (mg) forms an oxide with one magnesium atom and one oxygen atom as its formula. which element below is likely to form an oxide with a similar 1: 1 formula? silicon, si sodium, na aluminum, al calcium, ca

Calcium will form similar kind of oxide.

Explanation:

Magnesium is an alkaline earth metal. It has two electrons in its valence shell and thus it can easily give these electrons to form dipositive ion.

Mg: 1s² 2s² 2p⁶ 3s²

Mg⁺²: 1s² 2s² 2p⁶ [full filled].

Now it will form monoxide with oxygen as: MgO

The calcium also belongs to same group and have two valence electrons in its outer shell and thus it can easily give these electrons to form dipositive ion.

Ca: [Ne] 3s² 3p⁶ 4s²

Ca⁺²: [Ne] 3s² 3p⁶ [full filled].

hence it will also form CaO.

For other elements

a) Silicon can form SiO₂

b) Sodium can form Na₂O

c) Aluminium can form Al₂O₃

the temperature of the gas, in k, not celsius.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
