Answer:
1. most of the space inside an atom is vacant.
2. there is a tiny dense nucleus on the centre of atom.
Explanation:
since most of the alpha particle ere unscattered on passing through the gold foil he said that most part of atom is vacant. also as some alpha particle got strongly deflected on passing through the center he also made conclusion that the nucleus is small and positively charged and at the center of atom.
Answer: reduce the number of electrons.
Explanation:
to become electrically neutral. to rearrange its configuration to result in a complete outer energy level. add electrons to have a stable octet in its outer energy level
Answer:
When the following redox equation is balanced with smallest whole number coefficients, the coefficient for the iodide ion will be __6__.
Explanation:
From the redox equation, we can see that NO₃⁻ is reduced to NO (from oxidation state +5 to +2), whereas I⁻ is oxidized to I₂ (from oxidation state -1 to 0). The half reactions are balanced with H⁺ (acidic solution), as follows:
Reduction : 2 x (NO₃⁻(aq) + 3 e- + 4 H⁺ → NO(g) + 2 H₂O)
Oxidation : 3 x (2 I⁻(aq) → I₂(s) + 2 e-)
----------------------------------------------------------------------
Total equation: 6 I⁻(aq) + 2 NO₃⁻(aq)+ 8 H⁺ → 3 I₂(s) + 2 NO(g) + 4 H₂O
That is the redox equation with the smallest whole number coefficients.
Accordin to this, the coefficient for the iodide ion (I⁻) is: 6.
