Answer : The atomic models that belongs to the same element are atomic model 2 and 3. (Shown below)

Explanation :

As we know that an atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.

The protons and the neutrons are located inside the nucleus or center of the nucleus where the mass of the an atom is concentrated and the electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Same element has same number of protons.

Atomic model 1 : In this model, there are 8 number of electrons, 8 number of protons and 8 number of neutrons.

Atomic model 2 : In this model, there are 5 number of electrons, 5 number of protons and 6 number of neutrons.

Atomic model 3 : In this model, there are 5 number of electrons, 5 number of protons and 5 number of neutrons.

Atomic model 4 : In this model, there are 6 number of electrons, 6 number of protons and 6 number of neutrons.

From this we conclude that, the atomic model 2 and 3 has same number of protons. So, these two models belongs to the same element.

Hence, the atomic models that belongs to the same element are atomic model 2 and 3. (Shown below)

Answer from: Quest

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.

Answer from: Quest

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.
