Silicon gains 4 electrons.
Se will gain electrons
The silicon chip is in many devices today....ex. mp3 players. It was a major breakthrough because it allowed more technology to be stored in portable or smaller devices. Almost everything has a silicon chip..even your cell phone. Particularly the computer industry it was important to forthe same reasons. The iPad is a computer, so is the iPhone. But they wouldn't be possible without the silicon chip:)
Sorry but that question can not be answer.
Today's computers are many times smaller than DNA computers.
Silicon, its cheap and nearly ideal. Many other things have been tried, but none has really seen widespread use due to one or more difficulties that occurred. Gallium Arsenide is expensive and has mostly been limited to use in high priced supercomputers where the speed improvement justifies the cost. Diamond & graphenes & carbon nanotubes all still have process problems. Silicon-Germanium alloy has seen some use, but not so much in digital devices.
it has gain 4 electrons
Se will gain electrons
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
It can lose 1.
it will lose 3 electrons
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
It must gain two electrons.
It will lose 2 electrons.
45
Selenium will gain two electrons and arsenic will gain three electrons
Si gains 4 electrons.
