Argon, neon, and xenon are examples of a) halogens b) metalloids c) noble gases d) alkali metals

Argon, neon and xenon are examples of noble gases.

C is correct option.

Explanation:

According to electronic configuration

Argon:

The atomic number of argon is 18.

The electronic configuration of argon

Ar= 2,8,8

Neon:

The atomic number of argon is 10.

The electronic configuration of argon

Ar= 2,8

Xenon:

The atomic number of argon is 54.

The electronic configuration of argon

Ar= 2,8,18,18,8

Argon, neon and xenon are examples of noble gases because the last shell is completely filled and they does not participate in any reaction so, these atoms are called noble gasses.

Hence, Argon, neon and xenon are examples of noble gases.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
