The outer shell of an atom is most stable or non reactive with 8 electrons. 1 or 2 valence electrons would be reactive. It also would depend if it's bonded with another element.

How much valence electrons do berylium got?
Beryllium has two valence electrons.
How many valence electrons are in o?
O - Oxygen has 6 valence electrons.
What is the charge of valence electrons of calcium?
Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).
Are valence electrons the number of protons?
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many non-valence electrons does a neutral boron atom have?
There are two non-valence electrons in a neturol boron atom. The electronic configuration of neutral boron is 1s2, 2s2 2p1. The three electrons in the 2d shell are the valence electrons; the non--valence electrons are in the 1s orbital.
Which noble gases does not have 8 electrons in its highest occupied enegry level?
All noble gasses have 8 valence electrons, it is what makes them "stable" and therefore are non reactive.
What is the number of valence electrons for He?
Two valence electrons.
How many valence electrons Be have?
Beryllium has two valence electrons.
How many valance electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
In a reaction how many valence electrons will probably gain two electrons or share two covalent bonds?
In a reaction u need two valence electrons to gain or share two valence electrons.
