Without a charge, it would be 35 electrons. Protons have a positive charge and electrons negative. They must balance each other out, otherwise the atom will be charged.
Energy convention: Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles. Convection is one of the fundamental ways that heat is transferred
