The valance energy level contains 4 electrons in carbon.
Iodine has 7 valance electrons
The valency of an element refers to the combining power of a given element. The valencies of all the elements is contained in the table of valencies. The valencies of the elements can be obtained by looking at the groups in the periodic table.
Carbon has four valence electrons. Each of theseelectrons can pair with an electron from another atom to form a strong covalent bond. In carbon, all the electrons with the principal quantum number 2 are valence electrons, but the two electrons with principal quantum number 1 are not.
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
4 valence electrons dude!
The valance energy level contains 4 electrons in carbon.
Halogens are group 17 elements. They have 7 valence electrons.
Group I A elements have 1 valance electron.
6 Use the periodic table as a guide. As you go across from left to right the number of valence electrons increases. H = 1 Be = 2 B = 3 C = 4 N = 5 O = 6 F = 7 This trend stays the same all the way down each column. Usually periodic tables are marked on the top with roman numerals or something to signify how many valence electrons each element has.
2 valance electrons
There are 27 valance electrons.
Iodine has 7 valance electrons
The valency of an element refers to the combining power of a given element. The valencies of all the elements is contained in the table of valencies. The valencies of the elements can be obtained by looking at the groups in the periodic table.

The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
