Question

Antiparticles look and behave just like their corresponding matter particles, except?

1) They have opposite charge
2) They have opposite spin
3) They have opposite mass
4) They have opposite color

Answer 1

Antiparticles are similar to their matter counterparts but have an opposite charge, same mass, and generally the same quantum numbers. An example is the positron, which is the antiparticle of the electron with the same mass but a positive charge.

Step-by-step explanation:

Antiparticles behave similarly to their matter counterparts but have certain opposing properties. When addressing the question of how antiparticles are different from regular matter particles, the correct answer is that they have an opposite charge. Despite having opposite charges, antiparticles share the same mass and, except for neutrinos, the same quantum numbers as their respective particles. For example, an antielectron, also known as a positron, has the same mass as an electron but carries a positive charge. If a particle and its antiparticle meet, they annihilate each other, releasing energy in the form of photons.
