Answer: D) It has two more electrons than protons.
Explanation: Sulphur (S) is an element with atomic number 16 and thus contains 16 electrons. A neutral atom contains equal number of protons and electrons.
![S:16:[Ne]3s^23p^4](https://tex.z-dn.net/?f=S%3A16%3A%5BNe%5D3s%5E23p%5E4)
An atom on losing electrons gains positive charge and on gaining electrons gain negative charge.
Sulphide ion 
is formed by gaining 2 electrons to attain stable configuration of argon and thus contains two more electrons than protons.

Answer:
The statements that describe sunspots is;
D. Sunspots have lower temperatures than their surroundings
Explanation:
Sunspots is a phenomenon that involves temporary appearance of dark areas on the Sun's surface, which are regions of concentrated magnetic field flux which inhibit heat transfer by convection and are therefore cooler than other parts of the Sun. Due to the presence of magnetic field magnetic
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Opposite magnetic polarity sunspots usually appear as a pair.
Therefore, the statement that best describe sunspots is that a sunspot is a region of reduced temperature compared to surrounding areas on the Sun's surface.
