Explanation:
From the scattering experiments, Rutherford concluded that the positive charge was concentrated in the nucleus of the atom.
This contradicted the plum pudding model, which assumed that the positive charge was uniformly distributed throughout the atom.
The correct answer is option 2. When the pH of a solution is changed from 4 to 3, the hydronium ions increases by a factor of 10. pH is a scale used to measure the acidity or
alkalinity of an aqueous solution. It can be used to calculate the amount of
hydronium ions in the solution. It is expressed as: pH = -log [H+].
Answer:
An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.
