How many electrons are there in the helium atom?
7 Helium contains two electrons in all naturally occurring states.
How many unpaired electrons in Cesium?
C2 (short for carbon anion) has only two unpaired electronics located inside of it. It also includes two paired electrons and this is due to the fact that when a molecule becomes an anion, it means that is have gained 2 electrons. Therefore, giving it a pair (4) electrons all together.
Which of the electrons only allows a total of 2 electrons?
I think you mean what atom only allows a total of 2 electrons and that would be helium.
How does the number of valence electrons change?
There is no simple answer to your question, as your question is too broad and undefined. For simple atoms, the number of valence electrons is the number of electrons in unfilled electron shells, which are then available for bonding to another atom. Oxygen with 8 total electrons has 6 paired electrons in filled electron orbitals, and 2 valence electrons in unfilled orbitals. That is why it forms bonds with 2 hydrogen molecules to form water (H2O) The number of valence electrons can change when you add or remove electrons from an atom, or in more complex atoms where filled orbitals to unfilled orbitals have the same energy and electrons can move from one to another depending on the number of other atoms it is binding with.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How many paired electrons does boron have?
boron has 2 pairs
SO3 2- is diamagnetic or paramagnetic?
Diamagnetic. All of the electrons are paired.
What is the formal charge of chlorine in HClO?
[total # valence electrons] - [# lone electrons + 1/2(# paired electrons)] 20 - [4+1/2(10)] = 11 So, 11 is the formal charge.
How many electrons are there in the helium atom?
7 Helium contains two electrons in all naturally occurring states.
How many unpaired electrons are there in the Lewis structures of an N3- ion?
All of the electrons are paired. If you are asking how many lone pairs, there are 4.
How many unpaired electrons are in sulfur?
The answer is two.Third shell of sulfur is occupied by 6 electrons:3s2 3px2 3py 3pzof which the first 4 electrons (in 3s2 3px2) are paired (superscipted 2 means 2electrons per sublevel)and the other 2 electrons are unpaired (3py 3pz, no superscript means 1 electron per sublevel).
What does is mean to say a charge is quantized?
It means the charge is an integer multiple of some basic charge. If the charge consists of a certain number electrons, you can have 1 electron, 2 electrons, 3 electrons, etc., but you can't have 1.5 electrons, or pi electrons.
How many unpaired electrons does carbon have in its outer shell?
In a single carbon atom, there are two unpaired electrons. The electron configuration is:1s2 2s2 2p2where all the electrons are paired up except for the 2 in the 2p orbital, which are unpaired due to Hund's Rule

What is loanpair electron?
someone correct me if im wrong, but i think its electrons that are not used in the bonding of molecules, shown as 2 dots (or crosses, whatever you use) attached with a sort of bubble to the body of the molecule. Only 2 electrons are paired and in a bubble. hope that sorta helped =)
Which electron shell determines the chemical properties of an atom?
"Activity" as used in the question has no precise meaning, but I take it to mean reactivity. In VERY simple terms - Electrons can only have precise energies, those energies correspond to certain distances (orbitals or shells), from the nucleus. More than that, electrons are paired in each orbital so far as is possible. Both the energy of the electrons and whether they are paired determine how likely any atom is to form any particular type of bond, and also how many bonds, as bonding involves the gaining, loosing or sharing of electrons from the outer-most shell.
