The valence Electrons is 12!
In CH2O, there are a total of 12 valence electrons. Carbon shares 4 electrons, each hydrogen shares 1 electron, and oxygen shares 2 electrons. Therefore, a total of 10 electrons are being shared in CH2O.
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
3 electrons !
There are 7 valence electrons!🤓

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).

To determine the number of valence electrons in an electron configuration, look at the outermost energy level of the atom. The number of electrons in this level is the number of valence electrons.
