Sn has 50 total electrons and is in the Group 4a elements on the Periodic Table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
It is silicon that has the same number of valence electrons as carbon. Silicon sits right below carbon on the periodic table.
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 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!🤓
An atom of Sn (Tin) has 4 valence electrons in the 5th shell, so it has 4 p electrons.
It is silicon that has the same number of valence electrons as carbon. Silicon sits right below carbon on the periodic table.
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)
Two valence electrons.
the number of valence electrons is the number group on the table its on

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).
6 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.
