Interpretation : It must be explained why an atom has a positive charge when one or more of its electrons are lost.
Concept Introduction : The smallest constituent of an element that retains its identity throughout a chemical process is called an atom.
Answer to Problem 42A
Because there are fewer electrons in an atom when it releases electrons than the protons, the atom is left with a positive charge.
Explanation of Solution
J. J. Thomson's discovery of the electron, a negatively charged subatomic particle, revolves around the nucleus.
The positively charged subatomic particles known as protons were first found in the nucleus by Eugen Goldstein.
The number of protons and the number of electrons for an atom are the same.
If an atom loses an electron, a positive ion is formed. This is because the number of protons remains the same, but the number of electrons simply decreases.
