A. The charge on an element is determined by the differences between the number of protons and electrons in an atom.
An atom will have no charges if the number of protons and electrons are the same.
When an atom loses or gains electrons, the number of electrons will either decrease or increase
if the number of electrons is more than the number of protons, the excess electrons is the charge on the atom. And this makes the atom become a negatively charged ion.
if the number of electrons is lesser than the number of protons, the deficient electrons makes the atom a positively charged ion. The number of electrons by which the atom is deficient makes the atom a positively charged ion.
Charge = number of protons - number of electrons
B. Electrons form the charges they do because with the charge, they become stable like the noble gases.
The desire of every atom is to have stable electronic configuration like those of the noble gases.
A potassium atom with a configuration 2 8 8 1 will prefer to lose an electron to become an Argon atom making the ion stable.
The correct answer to this question is option D. A study area to the information in your study unit, the location that has to be the highest illuminance is the study room because it is the place the students can stay to study.
Yes because they atom with a stable octet electrons is less reactive it does not need any more electrons while an atom that has an partially filled electrons need more electrons to complete octet structure
The correct answer would be the first one. The reaction that will not conduct electricity would be CH3OH(l) = CH3OH(aq) since it stays as a single molecule in solution. It does not have any free electrons that will allow the flow of current into the solution. Other options dissociates into ions which has free electrons so they allow current to flow.
