Valence electrons are on the external shell.
Valence electrons
the electrons in the outermost shell of an atom are considered to be the valence electrons.
The valence shell is the outter most shell that contains the most electrons. To find out how many valences there are you would mulitply the electrons. C3H8= (6)3 + (1)8=26 the outer valence shell will be 20.
There would be six valence electrons in an atom of tellurium because tellurium is in Group 16 of the periodic table, so it has six valence electrons.

the number of valence electrons is the number group on the table its on
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.
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)
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.

To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
The valence electrons are found in the outermost energy level of an atom. To determine the number of valence electrons in an element, you typically look at its group number on the periodic table (columns 1-18), with the exception of the transition metals. Elements in the same group have the same number of valence electrons.
3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.
Electrons in the outermost shell are valence electrons!
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
