Question
elect the statement that correctly completes the sentence.An atom with one proton and one electron is electrically neutral. This means that the charge of an electron must be ____________ compared to the charge of a proton. half the sizethe same sizedouble the size
Solution
The correct statement to complete the sentence is "the same size". This is because in an atom, the number of protons (which are positively charged) is equal to the number of electrons (which are negatively charged) to maintain electrical neutrality. The charge of a proton is +1e, and the charge of an electron is -1e. Therefore, the magnitude of the charge of an electron is the same as the charge of a proton, but the sign is different.
