What else can I help you with?
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
How many valence electron are there in sodium neutral atom?
There is one valence electron in a neutral sodium atom. Sodium has an electron configuration of 2-8-1, indicating it has one electron in its outermost energy level.
How many electrons does cesium have to give up to achieve a noble gas electron configuration?
Losing an electron cesium has a noble gas configuration.
Hydrogen has how many valence electrons?
One. A hydrogen atom contains only one electron, and it is a valence electron.
How many electrons are in the valence shells of group 1?
There are 2 electrons in the first valence shell ("orbital"). The first orbital is an "s" orbital. If the atom is neutral in charge and there is only 1 electron - you have Hydrogen. If the atom is neutral in charge and you have only 2 electrons - you have Helium. Since the outermost shell of electrons is full, considerable chemical stability is conferred to the Helium atom, thus it is a member of the "Noble Gases" - those that have full comlpements of electrons in their outer shells, the others being Neon, Argon, Krypton, Xenon, and Radon.
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?

How many valence electron are there in sodium neutral atom?
There is one valence electron in a neutral sodium atom. Sodium has an electron configuration of 2-8-1, indicating it has one electron in its outermost energy level.
When is electron a valence electron?
A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
When is an electron a valence electron?
when it is on the very outside level away from the nucleusA valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.)It is an electron in the outermost shell of the atom.
How many electrons does cesium have to give up to achieve a noble gas electron configuration?
Losing an electron cesium has a noble gas configuration.
How many valence electrons does bromine wants?
Bromine wants to have 8 valence electrons to achieve a stable electron configuration, following the octet rule. Bromine has 7 valence electrons in its neutral state, so it typically gains one electron to reach the desired 8 valence electrons.
Hydrogen has how many valence electrons?
One. A hydrogen atom contains only one electron, and it is a valence electron.
How many valance electrons does hydrogen have?
Hydrogen has only one electron. Just the one. And it is a valence electron.
which element has 3 fewer electrons than neon when neutral?
All the elements in the first column of the Periodic Table (lithium, sodium, potassium, rubidium, cesium, and francium) have one valence electron. I also believe Helium has one valence electron.
How do you find the valence electron for groups one and two?
Group one has one valence electron, and group two has two valence electrons
How many valence electrons does the element cesium have?
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
