Discuss WGU Integrated Physical Sciences (C165, C908) Exam Topic 3 Question 1

The model above represents the parts of an atom. What type of particle is B?

AIon

BElectron

CProton

DNeutron

Suggested Answer: B

Understanding Atomic Structure: An atom consists of a nucleus made up of protons and neutrons, surrounded by electrons that orbit the nucleus.

Identifying Particles:

Protons (C): Positively charged particles located in the nucleus.

Neutrons (D): Neutral particles located in the nucleus.

Electrons (B): Negatively charged particles that orbit the nucleus in electron shells.

Ions (A): Atoms or molecules that have gained or lost one or more electrons, giving them a net charge.

Analyzing the Model: In atomic models, the particle labeled 'B' is typically shown in the electron shell or orbit around the nucleus, indicating it is an electron.

Conclusion: Particle 'B' is an electron.

Basic Atomic Structure: Fundamental concepts of atomic particles and their locations.

Electrons are outside the nucleus, right?

Cletus 6 months ago

I feel confident it’s an electron.

Leonida 6 months ago

No way, protons are in the nucleus.

Remedios 7 months ago

I’m not sure, could it be a proton?

Genevive 7 months ago

Nope, it's an electron for sure!

Minna 7 months ago

I thought neutrons were the neutral ones, not electrons?

Sheridan 8 months ago

Wait, are we sure? Could it be a proton?

Cherry 8 months ago

Totally agree, it's the only option that makes sense.

Ira 8 months ago

Hmm, I'm torn between B and C. Guess I'll just go with my gut and pick the electron.

Rosio 8 months ago

B, the electron, no doubt. Gotta love these basic atom questions.

Merilyn 8 months ago

Haha, this is easy. It's obviously D, the neutron. What else could it be?

Sue 8 months ago

I'm going with C, the proton. The model clearly shows the central core of the atom.

Celestina 9 months ago

Definitely B, the electron. That's the only particle that fits the description.

Serina 9 months ago

I feel confident that B is an electron. The image looks like it shows the electron cloud around the nucleus.

Joesph 9 months ago

I'm a bit confused because I can't remember if B could also be a proton. I need to double-check my notes.

Ligia 9 months ago

I've got this! B is definitely the electron. The diagram clearly shows the different particles that make up an atom, and the electron is one of the key components, so that has to be the answer.

Aleshia 9 months ago

I'm a bit confused by this question. The diagram shows the parts of an atom, but I'm not sure which one corresponds to B. I'll have to review my notes on atomic structure to figure this out.

Madelyn 9 months ago

Okay, based on the diagram, I'm pretty sure B is the electron. The electron is one of the main components of an atom, so that seems like the most likely answer.

Flo 10 months ago

I practiced a similar question last week, and I think B definitely refers to an electron.

Reynalda 10 months ago

I think B is an electron, but I'm not completely sure. I remember electrons are negatively charged.

Serina 10 months ago

B is definitely an electron!

Deandrea 10 months ago

I think B is an electron.

Marlon 10 months ago

Yeah, electrons are negative.

Sage 11 months ago

Hmm, I'm not totally sure about this one. The diagram looks like it's showing the structure of an atom, but I'm not confident which particle B represents. I'll have to think this through carefully.

Joana 11 months ago

I think B is the electron, since the diagram shows the different parts of an atom and the electron is one of the key particles.

↳ replying to Joana

So true! What about the other options?

Doug 6 months ago

↳ replying to Joana

Right! They orbit around the nucleus.

Tom 6 months ago

↳ replying to Joana

Definitely! Electrons are crucial in atoms.

Jacqueline 6 months ago

↳ replying to Joana

I agree, B must be the electron!
