Answer: Winds and currents flow faster at the equator than at the poles. One reason equatorial currents are faster is that they are warmer. Another reason is that the speed of the Earth's rotation is much faster at the equator.
That in the ground state of an atom or ion electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. The electrons of a atom or ion form the most stable electron configuration possible .
Since an alpha particles is a helium nucleus, it involves the loss of 2 protons and 2 neutrons. As a result, the atom the loses an alpha particle decreases its mass number by four ( 2 protons and 2 neutrons) and decreases it's atomic number by 2 ( it loses two protons).

Reduction half reaction: Cu²⁺(aq) + 2e⁻ → Cu⁰(s).
Oxidation half reaction: NO₂⁻(aq) + H₂O(l) → NO₃⁻(aq) + 2H⁺(aq) + 2e⁻.
Balanced chemical reaction:
Cu²⁺(aq) + NO₂⁻(aq) + H₂O(l) → Cu(s) + NO₃⁻(aq) + 2H⁺(aq).
Copper is reduced from oxidation number +2 (Cu²⁺) to oxidation number 0 (Cu) and nitrogen is oxidized from oxidation number +3 (in NO₂⁻) to oxidation number +5 (in NO₃⁻).
