Which prediction about a methane molecule would most likely be made by using both the quantum model of the atom and john dalton's model? a. when the molecule reacts new atoms are created b. the molecule contains different kinds atoms c. the nucleus is located in the center of the molecule d. electrons are located at specific locations in the molecule.

B.the molecule contains different kinds atoms

Explanation:

Let's go through each choice.

A.when the molecule reacts new atoms are created

Both quantum model of the atom and John Dalton's model recognize that the atoms are not either created or destroyed in a chemical reation, so when a molecule reacts it forms one or more new molecules with the same atoms of the original molecule.

B. the molecule contains different kinds atoms

Indeed, John Dalton's model already considered that the compounds (molecules) are formed by the combination of different kinds of atoms. This is valid nowadays under the quantum model.

C. the nucleus is located in the center of the molecule

Firstly note that John Dalton's model did not consider the existence of a nucleus as the atom was thought to be indivisible. Secondly, quantum model considers that the nucleus is at the center of the atom, not of the molecule.

D. electrons are located at specific locations in the molecule.

John Dalton's model did not consider that the existence of electrons, since, as already said, the atoms was considered indivisible. Regarding quantum model, electrons are not located at specific locations but the model states the probability of finding the electrons in certain regions. The regions with high probability of containing the electros are called orbitals.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
