Answer:
-1
Explanation:
An atom contains a proton, electron and neutron as subatomic particles. The number of protons, which is the positively charged particle (+) is always equal to the number of electrons, which is the negatively charged particle (-) in A NEUTRALLY CHARGED ATOM i.e. no charge.
However, a decrease or increase in charge is dependent on the number of electrons and protons in that atom. Sulfur atom has an electron number of 16 in its neutral atom, however, when it gains one more electron to become 17, it means that the charge has become -1 because the charge = number of protons - number of electrons i.e. 16 - 17 = -1.

Answer:
There is an attractive force between the rod and sphere.
Explanation:
When negatively charged rod is placed close to the metal sphere then due to the electric field of the rod the opposite free charge of metal sphere comes closer to the rod on one surface
While similar charge in the metal sphere move away from the rod due to repulsion of electric field of rod
This temporary charge distribution of the metal sphere is known as induction
And since opposite charge on the metal surface comes closer to the metal sphere so here we can say that the rod will attract the metal sphere
so here correct answer will be
There is an attractive force between the rod and sphere.
