Good question. Because you don't dwell in the quantum world. A lot of the quantum world is simply averaged into the macro world so it is not observable. While YOU can't be in two places at once, some of the electrons in you body can...and DO! One of the wonderful things about science is that it discloses ABSOLUTELY STUNNING realizations about the true nature of reality. Study more and be amazed.
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
No. No two elements have the same electron configuration.
Four electron groups - two bonded pairs and two lone pairs
Zinc is an electron donor; by giving away two electrons, it becomes Zn2+.
The name of the group of elements with two valence electron in each atom is "alkaline earth metals."
because the moon can't be i two places at once.
Probably.
Energy cannot be destroyed. It can be transformed, transmuted, and can be in two places at once; www.canask.org
How Can You Be in Two Places at Once When You're Not Anywhere at All was created in 1969.
Yes. That's why only photons (no rest mass) can be in two places at once.
Government cannot hold two positions at once for one reason. The reason that government cannot not hold two positions at once is so everyone will have a chance at term.
You have to decide which place to go.
That's possible.
A bilocation is the ability to be, or the state of being, in two places at once.
If you use two seperate accounts, you can. You cannot be logged onto the same account in two clients at the same time. Once you log into on client, and then the other, it will disconnect the first client.
You can Straddle a state border :D that's the only exception to being two places at once that I can think of
No, because neutral hydrogen has only one electron - so it cannot lose TWO.
