Valence electrons are those electrons that are found on the shell or orbital that is furthest away from the nucleus of an atom. So for example in the case of Sodium which has 3 shells, as can be deduced from it electronic configuration 2.8.1, the single electron on the third shell would be the valence electron of Sodium.
Answer:
Botched surgery, inhaling harmful toxins and smoking.
Explanation:
Smoking is a death wish.
True
as a compound tends to be formed from the reaction between two or more elements to produce stable compounds if they had a charge they would be classified as an ion

So,
Ionic compounds are compounds composed of ions. The following are soluble ionic compounds (they dissolve in water):
NaCl(s) --> Na⁺(aq) + Cl⁻(aq)
NaOH(s) --> Na⁺(aq) + OH⁻(aq)
The following are insoluble ionic compounds (they have low solubilities):
Al₂O₃ --> 2Al³⁺+3O²⁻
AgCl --> Ag⁺ + Cl⁻
These compounds can only be appreciably separated by melting or by dissolving them in enormous amounts of water (the concentration will still be very low).
Ionic compounds have electrons that are locked in place because of the strong ionic attractions between the ions. A charge is produced by moving electrons. Since the ions in melted ionic compounds are free to move, their electrons are no longer locked, allowing the ionic liquid to conduct electricity.
NaCl(s) --> Na⁺(l) + Cl⁻(l)
The answer is D.
