When an atom has an equal number of electrons and protons it has an equal number of negative charge (the electrons) and positive electric charges (the protons). The total electric charge of the atomic is therefore zero
The outer electron in magnesium is excited by absorbing the heat energy from the N=1 stage to higher energy levels when it starts to drop back down to the N=2 level it losses energy in the form of visible light this is part of the Balmer series

Answer:
Carbon-Carbon Bonds
Carbon can form single, double, or even triple bonds with other carbon atoms. In a single bond, two carbon atoms share one pair of electrons. In a double bond, they share two pairs of electrons, and in a triple bond they share three pairs of electrons
Answer:
CH3O- , OH-, NH-2
Explanation:
The given nucleophilic compounds:
Hydroxide, OH-, Ammonia, NH3, Water, H2O, Methanol, CH3OH, Methoxide, CH3O-, Cyanide, CN-, Amide, NH2-
<u>Nucleophile capable for doing E2reaction:
</u>
Generally strong basic compounds are used for E2- Elimination. Because in E2 - elimination proton abstraction and leaving group leaving happen on same time so we need strong base for E2-elimination.
In the given compounds only CH3O- , OH-, NH-2, are strong basic compounds so these compounds only capable for doing E2-Elimination.
