Question

which statement describes a property of a proton?
○ is found outside the nucleus
○ has a positive charge
○ has less mass than an electron
○ is repelled by electrons

Explanation:

• "is found outside the nucleus": Protons are in the nucleus, electrons are outside. Eliminate this.
• "has a positive charge": Protons have a +1 charge, neutrons neutral, electrons negative. This is correct.
• "has less mass than an electron": Protons have much more mass than electrons. Eliminate.
• "is repelled by electrons": Protons (positive) attract electrons (negative), not repel. Eliminate.

Answer:

B. has a positive charge (assuming the options are labeled A, B, C, D with A as "is found outside the nucleus", B as "has a positive charge", C as "has less mass than an electron", D as "is repelled by electrons")
