Answer:
Sulfur dioxide (SO2)
⇒ Why is this the best option?
To determine the polarity of the molecule, there are two requirements. The first one has a variety of terminal atoms, whereas the second has a lone pair on the center atoms. The molecule is polar if one of the requirements is met; else, it is nonpolar. The oxygen atom is a terminal atom because it surrounds the sulfur atom, which is the center element in the SO2 molecule's Lewis structure. In this molecule, there are two terminal oxygen atoms. If we look at the first criterion, we can see that it is not met because it calls for the presence of two separate terminal atoms.

Answer:
1. Protons
2.Neil Bohr model
3.shell
4.results and conclusion for gold foil experiment
The protons are not scattered uniformly but they are concentrated at the nucleus (core) of the atom
The nucleus is largely responsible for the entire mass of the atom.
There is an empty space surrounding the nucleus and the electrons revolve round an orbit at a distance from the nucleus
5. the s orbital has the least amount.
Explanation:
the maximum capacity for s orbital is 2.
Answer: During a phase change, such as melting or boiling, the kinetic energy increases.
Explanation:
Kinetic energy is the energy obtained by the molecules of a substance due to their motion.
When phase change such as melting or boiling takes place then it means heat is absorbed by the substance. As a result, their molecules more even more rapidly from one place to another due to which more number of collisions take place.
Hence, a change in phase of substance occurs as kinetic energy increases in melting or boiling process.
Thus, we can conclude that during a phase change, such as melting or boiling, the kinetic energy increases.
Epsilon-delta would be the green letter that is used in the precision definition of a limit. (ε, δ).
