Helium
The maximum number of electrons in the second energy level of an atom is 8.
In the second energy level, eight electrons are allowed at most.
eight(8)
The second energy level contains eight valance electrons when it's full.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Xenon has a total of 54 electrons. The highest occupied energy level of xenon is the 5th energy level, which can hold a maximum of 18 electrons. Therefore, on the highest occupied energy level of xenon, there are 18 electrons.
The most valence electrons an atom can contain is eight.
there are eight electrons.
Eight.
The answer is 4s, because it is in the 4rth period of the Periodic Table of Elements =]
The maximum number of electrons in the second energy level of an atom is 8.
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
In the second energy level, eight electrons are allowed at most.
In argon, there are 18 electrons in total. Energy level 3 can hold a maximum of 18 electrons, but since argon's electron configuration fills up the lower energy levels first, energy level 3 in argon will have its maximum capacity of 8 electrons.
eight!!
