Everything in the universe if 4-D, but not in that sense. According to Einstein the 4th dimension is time itself. He used a good analogy: Say you are talking on the phone to a friend, and you want to meet. And he is on the 6th floor of an apartment building in apartment 4b. There you have 3 dimensions, but you are missing something: the time. Without that your meeting would surely be miscommunicated.
Yttrium (Y) has an atomic number of 39, which means it has 39 electrons. Its electron configuration is [Kr] 5s² 4d¹, indicating that there is one 4d electron in yttrium. Therefore, the number of 4d electrons in Y is 1.
The element with 3 valence electrons in the 4d sublevel is Yttrium (Y). It is located in group 3 of the periodic table and has an atomic number of 39. In its electron configuration, Yttrium has the outer configuration of [Kr] 4d¹ 5s², contributing three valence electrons from the 4d and 5s orbitals.
Actually, no one knows if anything can last forever. No one knows the future of the universe. One theory has this universe expanding and then collapsing into a big crunch where everything will be destroyed. Another theory has the this universe bleeding into others in which case it is possible for material to last for a much longer period of time.
The electronic configuration of niobium (Nb) in its neutral state is ( [Kr] 4d^4 5s^1 ). When niobium loses four electrons to become Nb(^{4+}), the configuration changes to ( [Kr] 4d^4 ), as the 5s and three of the 4d electrons are removed. Thus, the electronic configuration for Nb(^{4+}) is ( [Kr] 4d^4 ).
It hasn't stopped. If anything it is expanding faster than ever.
The concept of a 4D universe suggests that space and time are interconnected and can be viewed as a single entity. This challenges traditional notions of space and time as separate dimensions. It implies that our understanding of the universe may need to be reevaluated to account for this interconnected nature, potentially leading to new insights and perspectives on the nature of reality.
8 - 4d = 12-4d = 4d = -1
No, there is not there is no edge to the universe, and there is nothing outside of the universe. there just IS the universe.
4d is time...any moving object is 4d
there is no 4d known to man
2-4d = -2
The universe does not orbit around anything. It is constantly expanding and there is no central point or object that it revolves around.
Sometimes you only see 4D for short times, normally our 3D in 4D surface is not contacted, and sometimes it can be that the 4D thing stays on.
No.
There's no such thing as 4D cinema. It's 2D or 3D. There is no 4D cinema.
I think your question should have been When instead of where. There are several theories.The Big Bang is perhaps the most popular theory. It consisits of an atom which exploded thus expanding slowly forming more matter than antimatter.Another theory is of parallel universes. Our universe is like a sheet of paper and is swinging adjuscent to our sister universe. At one point of time they come in contact with each other and that unleashes a tremendous amount of force which either annihlate one or creates a new one in the other.Another is a new theory which suggets that our universe is like a 3D Event horizon of a 4D black hole in a 4D universe. Its called hyperspace.
It is: 2(4d) = 8d
