there are 6 valence electrons in each element in group 16
Calcium has 20 electrons
The d block of the periodic table contains 10 valence electrons.
period 3 elements in the periodic table have 3 electrons in there outher shell hence the name.
Xenon has 54 electrons.
Chlorine has 17 electrons. It is displayed as atomic number in periodic table.
Just so you know, the periodic table does not give any indication of how many electrons an atom has but 95% of sulfur atoms are neutral and so contain 16 electrons.
Chlorine (Cl) has 7 valence electrons, as it is in Group 17 or 7A of the periodic table. This means it has 7 electrons in its outermost energy level.
As is present in group-15. It has 5 valence electrons.
By the [use and] study of the Periodic Table.
For example the elements from the group 1 of the periodic table.
how many electrons it has---how many valence electrons and how many levels of electrons. its Atomic Mass its atomic number
2 electrons.
