Chemical bonds, either ionic or covalent bonds. These electrons hold atoms together into molecules. They can be shared by atoms (in a covalent bond) or given from a metal to a non-metal. The donor atom becomes positively charged (because it now has more protons than electrons), and the recipient atom becomes negatively charged. The atoms then bond due to the electrical attraction. A good example is table salt, NaCl, which is really Na+ and Cl-.
So valence electrons are really the ones involved in ... chemistry!
What else can I help you with?
What is Number of valence electrons of cobalt?
There are ONLY 2 valence electrons in Co, valence electrons come only from the s orbital and the p orbital, giving only 2 for Cobalt.
Which electrons are use to form bonds?
Valence electrons are the electrons that are used to form bonds between atoms. These are the electrons in the outermost shell of an atom.
Which has more valence electrons potassium or calcium?
Calcium has more valence electrons than potassium. Potassium has only 1 valence electron, while calcium has 2 valence electrons.
Which element has the fewest valence electrons?
Helium has the fewest valence electrons, with only 2 valence electrons.
How many electrons does Ba has?
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
What is a noble gas but does not have 8 valence electrons?
Helium is the only noble gas that doesn't have 8 valence electrons. It only has 2.

What is the Valence electron in He?
helium has only one shell with two electrons and can be considered to be as the valence electrons.
How valence 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.
