Answer:
A. Forming a positive ion!
Hope this helped :)
Explanation:
The chemical formula magnesium sulfide written as MgS and NOT
because charge on magnesium ion is +2 and charge on sulfide ion is -2.
Therefore, these charges will cancel out each other as we write the formula in simplest crisscross method.
Also, the numbers in a chemical formula display the total number of atoms attached with each other or central atom.
For example, in
there are two chlorine atoms attached to one calcium atom.
Therefore,
denotes one sulfur atom is attached to magnesium atom. Hence, we do not write the formula of magnesium sulfide as
because this shows two magnesium atoms are attached to two sulfur atoms which is not true.
Bright Line Emission Spectrum: As the excited electron returns to ground state (it's lower energy level) the energy it originally absorbed is released as discrete lines of light.
If your in a city, go inside a building immediately. most buildings have lightening rod, so the lightening voltage won't hit on you.
if you're in an open area, don't go under a tree, or it'll hit you and the tree, even if it doesn't hit you, you still cannot take the impact by the exploding tree. leave the water or metal bicycle or stuff that conducts electricity.
