Characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.
<h3>What is atomic theory?</h3>
Atomic theory is the scientific theory that matter is composed of particles called atoms.
The discoveries of subatomic particles such as;
- electron by J.J. Thomson
- proton by Ernest Rutherford
- neutron by James Chadwick
- nucleus by Ernest Rutherford
all contributed in the development of the atomic theory.
From the information given in the passage J.J. Thomson experiment gave rise to atomic model while Rutherford, Geiger and Ernest Marsden, performed the experiment that discovered nucleus and proton.
Thus, characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.

Gold (III) nitrate in an aqueous solution is hydrolyzed with formation of gold (III) metahydroxide.
Au(NO₃)₃ → Au³⁺(aq) + 3NO₃⁻(aq)
Au³⁺ + H₂O ⇄ AuOH²⁺ + H⁺
AuOH²⁺ + H₂O ⇄ Au(OH)₂⁺ + H⁺
Au(OH)₂⁺ + H₂O → AuOOH·H₂O(s) + H⁺
Au(NO₃)₃(aq) + 2H₂O(l) = AuOOH(s) + 3HNO₃(aq)
Explanation:
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.
