Magnesium metal with the electron configuration 3S ^ 2 with the nonmetal Fluorine with the electron configuration 2s^ 2 2p^ 5 The correct chemical formula is A) Mg 2 F B) Mg 2 F D) MgF 2

The electron configuration of magnesium is [Ne] 3s 2. It is an s block element, and it occurs as a solid at standard temperature and pressure. It is a shiny grey metal. The melting point and boiling points are 650 °C and 1091 °C respectively. The most common and stable oxidation state is +2, but it can form +1 oxidation state as well. In writing the electron configuration for Magnesium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for magnesium go in the 2s orbital. The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2.

Explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
