Magnesium has two valence electrons and oxygen has six valence electrons. The electronegativity difference between the two elements is 2.13.
How can the octet rule be used to explain the bonding between magnesium and oxygen?
Oxygen needs access to two electrons to satisfy the octet rule. Magnesium prefers to lose two valence electrons to satisfy the octet rule. Oxygen can remove two electrons from magnesium, forming ions; leading to an ionic bond.
Oxygen needs to lose six electrons to satisfy the octet rule. Magnesium needs access to six valence electrons to satisfy the octet rule. Magnesium can remove six electrons from oxygen, forming ions and leading to an ionic bond.
Oxygen needs access to two electrons to satisfy the octet rule. Magnesium prefers to lose two valence electrons to satisfy the octet rule. Magnesium and oxygen can share two electrons, leading to a covalent bond.
Oxygen needs to lose six electrons to satisfy the octet rule. Magnesium needs access to six valence electrons to satisfy the octet rule. Magnesium and oxygen can share six electrons, leading to a covalent bond.
c?
is it D
Yes, you are correct. The correct answer is c) Oxygen needs access to two electrons to satisfy the octet rule. Magnesium prefers to lose two valence electrons to satisfy the octet rule. Magnesium and oxygen can share two electrons, leading to a covalent bond.
Yes, option c is correct. The octet rule states that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration with a complete outer shell of eight electrons (except for hydrogen and helium, which only require two electrons).
In the case of magnesium and oxygen, magnesium has two valence electrons and prefers to lose those electrons to achieve a stable electron configuration. Oxygen has six valence electrons and needs access to two more electrons to satisfy the octet rule.
Therefore, magnesium and oxygen can form a covalent bond by sharing two electrons. This allows both atoms to attain stable electron configurations—magnesium loses its two valence electrons, while oxygen gains two electrons through sharing. The resulting compound, magnesium oxide (MgO), is held together by this shared pair of electrons in a covalent bond.
