Question

Electron configuration of Oxygen, Magnesium, and carbon​

Answer 1

Answer:

Oxygen is the eighth element with a total of 8 electrons. In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the O electron configuration will be

the configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.

Answer 2

Carbon =He] 2s2 2p2

Magnesium =electron configuration will be 1s2 2s2 2p6 3s2.

Oxygen =electron configuration will be 1s2 2s2 2p4.
