Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
Elements in the 16th group has 6 electrons in their outermost energy level. That means they have 6 valence electrons. Oxygen,Sulfur are in the 16th group.
The no. of valence electrons in group 16 is 6
Elements in group 16 are in the p block, and will have 6 valence shell electrons. So, the general configuration will be ns2 np4 with n corresponding to the period.

A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
A neutral atom of fluorine contains 7 valence electrons.
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
There are two non-valence electrons in a neturol boron atom. The electronic configuration of neutral boron is 1s2, 2s2 2p1. The three electrons in the 2d shell are the valence electrons; the non--valence electrons are in the 1s orbital.
A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
they all have one valence electron.
Group 16 (VIB or VIA) elements have six valence electrons.
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
Valence electrons are the electrons from the outermost shell of the atom. Number of valence electrons in an atom = the group number of that atom Valence electrons of a moleucle = sum of the valence electrons of all the atoms in that molecule. The molecule HCl has 1 hydrogen (group number =1) and 1 chlorine atom (group number =7). The total number of valence electrons in HCl = 1(1) + 1(7) = 8 Pushpa Padmanabhan Lansing Community College
oxygen has 6 valence electrons as indicated by the 6A above the group oxygen is in
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
Phosphorus is a group 5 element. All group 15 elements have 5 valence electrons. Thus, phosphorus has 5 valence electrons.
A barium atom has two valence electrons.
