How many electrons are in each of the first two shells if an atom contains eight electrons?

∙ 11y ago
The first shell can have 2 electrons, the second shell has 8 electrons and the third shell has 8 electron also. No matter what, electron fill up the first shell and then move into the next shell and then the next one. To answer the question, the first shell would have 2 electron and then the second shell would have six.

How many electrons are needed to fill the first three electron shells?
6 electrons From the inside out, two, eight and eight.
How many electrons does each main energy level hold?
The first shell can hold up to two electrons, second up to eight electrons, third up to 18 electrons and the subsequent shells can have up to 32 electrons in each.
What is an atom shell?
electron shells are like the orbits of electrons around the protons and neutrons the atoms can have 1-3 shells
When full the innermost electron shell of argon contains how many electrons?
there are 2 completely full shells in argon. Argon= 18 electrons. 2 first shell 8 second shell (full) and 8 third shell (full)
How many occupied energy levels does a rubidium atom have?
Rubidium has 5 shells because the first shells has 1 electron, the next 2 shells have 8 electrons, the fourth shells has 18 electrons and the last shells has 2 electrons. the atomic number is 37, 1+8+8+18+2=37. Therefore Rb has 5 shells. :D
How many electron shells does an atom of oxygen have?
An oxygen atom has two shells. The first contains two electrons, and the second contains six electrons.
How many electrons are needed to fill the first three electron shells?
6 electrons From the inside out, two, eight and eight.
Which atom contains eight electrons?
Oxygen. Two of the electrons are in the first shell. The other six of them are in the second shell.
According to the oclet rule an atom with two electron shells is most stable when it contains eight?
The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main-group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons.ELECTRONS
Why is helium an exception to the noble gases?
A Noble Gas does not need to have eight electrons to be classed as such - it simply must have a full outer shell. The first shell can only hold two electrons, which is what helium has, so helium is a Noble Gas. The second and third shells hold eight electrons, which is why other noble gases can be seen as having eight electrons. However no Noble Gases have eight electrons in total - just eight in the outer shell, as the shells fill from the inside out...
Which atoms have twin electrons in the first shell and eight electrons in the second shell?
Neon, plus the other noble gasses, but these other noble gases also have additional electrons in outer shells.
How many electrons does each main energy level hold?
The first shell can hold up to two electrons, second up to eight electrons, third up to 18 electrons and the subsequent shells can have up to 32 electrons in each.
How does the Bohr model of the atom relate to the Periodic Table?
The Bohr model of the atom places electrons in orbits or "shells." Elements in the first period only have electrons in the first shell. Elements in the second period have electrons in the first two shells. Elements in the third period have electrons in the first three shells, and so on.
How many outer shells are there in magnesium?
There are two electrons in the outer shell and there are three shells in total. The first shell holds two. The second eight. Then the last is two.
How many electrons are in the first four shells of an atom?
2,8,8,8
Which element has 2 electrons in the first and second shells?
Beryllium
What is an atom shell?
