Electrons, Protons and the Atomic Number is the exact same. So 
Protons - 17
Atomic Number -  17

and the neutrons come by subtracting the protons from the Atomic Mass, which in this case 35. 
35-17 = 18
Neutrons = 18

Protons = 17
Atomic Number = 17
Neutrons = 18

3. Unlike global winds, local winds (select the two answers that are correct)
Viktor [21]

Answer:

Small-scale convection currents arise from uneven heating on a smaller scale. This kind of heating occurs along a coast and in the mountains. Small-scale convection currents cause local winds. Local winds blow over a much smaller area and change direction and speed over a shorter period of time than global winds.

Maybe that will help you answer the question.
