Question

10/20 what makes an atom have a positive charge? more neutrons than electrons more protons than electrons more electrons than protons less protons than electrons

Explanation:

To determine what makes an atom have a positive charge, we recall the charges of subatomic particles: protons are positive, electrons are negative, and neutrons are neutral. The net charge of an atom is determined by the balance between protons and electrons. If an atom has more protons (positive charges) than electrons (negative charges), the positive charges will outweigh the negative ones, resulting in a net positive charge.

• The green option (more neutrons than electrons) is incorrect because neutrons have no charge and do not affect the electric charge of the atom.
• The orange option (more electrons than protons) would result in a negative charge, as the negative charges would outweigh the positive ones.
• The blue option (less protons than electrons) is also incorrect as it is similar to the orange option in terms of charge balance (more negative charges), leading to a negative charge.
• The purple option (more protons than electrons) is correct because the excess positive charges from protons will give the atom a positive net charge.

Answer:

B. more protons than electrons (assuming the purple option is labeled B; if the original labels are different, adjust the label accordingly, but the content is "more protons than electrons")
