State whether the following statements are true or false :
(a) A sodium ion has positive charge because it has more protons than a neutral atom.
(b) A chloride ion has negative charge because it has more electrons than a neutral atom.
(a) False.
Explanation: A sodium ion carries a positive charge because it has less number of electrons than a neutral atom.
(b) True.
Explanation: A chloride ion carries a negative charge because it has more electrons than a neutral atom.
