Question

question 8 (1 point) (02.03 mc) the table shows the charge on two unknown subatomic particles: \
\

sub atomic particle	charge	\
---------------------	--------	\
a	negative	\
b	neutral	\

\
based on the quantum model, which of the following correctly compares the location of the subatomic particles?\
\
\\u25cb a particle a is packed in the nucleus, and particle b is present in shells.\
\\u25cb b particle a spirals into the nucleus, and particle b is packed in the nucleus.\
\\u25cb c particle a is embedded in a solid sphere, and particle b is present in the 3d orbitals.\
\\u25cb d particle a is present in the electron cloud, and particle b is packed in the dense center.

Explanation:

1. Recall subatomic particle properties: Electrons have negative charge, neutrons have neutral charge.
2. Locate particles: Electrons (negative, Particle A) are in the electron cloud. Neutrons (neutral, Particle B) are in the nucleus (dense center).
3. Analyze options:

• Option a: Electrons (A) aren't in nucleus, neutrons (B) aren't in shells. Incorrect.
• Option b: Electrons don't spiral into nucleus (quantum model), neutrons are in nucleus but A's description is wrong. Incorrect.
• Option c: "Solid sphere" is outdated (plum - pudding), neutrons aren't in orbitals. Incorrect.
• Option d: Matches electron (A in cloud) and neutron (B in nucleus/dense center) locations. Correct.

Answer:

d. Particle A is present in the electron cloud, and Particle B is packed in the dense center.
