Question

question 23
protons have ____.
a no charge
b a positive charge
c a negative charge

question 24
an ion can be formed by.
a the loss of a proton.
b the gain of a proton.
c the loss of an electron.
d the gain of an electron.
e the loss or gain of an electron.

Explanation:

Question 23

Protons are subatomic particles. By definition, protons carry a positive electric charge. Neutrons have no charge, and electrons have a negative charge. So option B is correct.

An ion is an atom or molecule with a net electric charge due to the loss or gain of electrons. Protons are in the nucleus and their number defines the element, so changing proton number changes the element, not forming an ion. Losing an electron gives a positive ion (cation), gaining an electron gives a negative ion (anion). So ions form via loss or gain of electrons (option E).

Answer:

B. a positive charge
