How many orbitals are in the 4d subshell?
One orbital - 6s which can hold 2 electrons.
How can tell whether or not an element will react with other elements?
On the periodic table, there are periods that are rows, and groups that are columns. Elements in the same group react like the other elements in the group.
Which is the odd one out out of aluminum magnesium sodium and silicon?
A couple of different cases could be made here, but the most obvious one is that silicon is the odd element out. The element magnesium is in Group 2, which is the Alkaline Earth metals. Both aluminum and lead are Poor Metals, and silicon is a Metalloid. The operative word for the first three elements is metal. And silicon is not one.

What is considered a pure substance?
Pureness is in the eye of the beholder. But monocrystaline minerals could be considered "pure" as could anything consisting of just one element or one compound.
What way can a scientists could really change copper into gold?
You can't. An element is the simplest form that anything can be broken down into.
Suppose you could see a 2s subshell and a 2p subshell. How could you tell them apart?
You can differentiate between a 2s and a 2p subshell based on their shape. The 2s subshell is spherically symmetric and has one orbital. On the other hand, the 2p subshell has a dumbbell shape and consists of three orbitals: px, py, and pz, each oriented along separate axes.
How would you use the periodic table to replace one of the elements in a new substance with another element that has similar chemical properties?
You would see which group the element was in and then replace it with another element from the same group, as all elements in a group have similar properties. For example you could replace Sodium with Potassium as they are both in Group 1.
How could you change equal representation in the senate?
No amendment could change equal representation in the senate without
What element in group 16 was known during the roman empire?
It could be Cobalt Ferrum erat. It was Iron.(Fe)
What determins an element?
You can determine what element an atom is by it's amount of sub-atomic particles and their positions. Every element has a different amount of electrons, so that is the easiest way to determine what type an atom is. If you wanted to determine it more broadly, for example, which group an element was in, you could just count the amount of electrons in the outer shell, as each group is unique in this way.
What element in group one has a higher atomic number than chlorine but lower atomic number than bromine?
It could be potassium(K)
What does 03.14. 16?
It does nothing. It consists of the first five digits of pi. It could be the representation of a date in the US style. It does nothing. It consists of the first five digits of pi.

Representation of a person in a historical context in which they could not have existed?
anachronism
What is the decimal representation of y?
We could answer that if we knew the value of 'y'.
Is 672 an element?
Not usually, but it could be an element of a set.
How can you identify if a new substance is made?
You would use trend of the periodic table to pinpoint the group or period of the substance. Then you would use group/period characteristics. If you can not find an element that matches, you will have to repeat the process which you created the element(if you created it). If you found the element then search around for more and team-up with a renowned chemist and prove it. ***It could take a few years to a coule decades to prove it***
What could the british have done to prevent the Americans reaction to taxes?
They could have allowed the colonies to have representation in the British Parliament. The colonists would not have minded taxation as much had there been representation from the colonies.
