All noble gasses other than helium which has 2
Group 15, 16, 17 and 18 elements have 5, 6, 7 and 8 valence electrons. (helium is the only exception in this, as it has only 2 valence electrons).
Group 0, or the first group from the left, have elements with filled valence shells. They are called noble gases.
Nobel Gasses
The Noble Gases.
Octet Element.
group 17 elements (halogens)
isotopes
Neon
Eight, except for helium which has two.
Number of valence electrons, that is, the number of electrons that the outer shell of an atom can hold. Ex. All halogens can have 7electrons in their outer shell. All gases have a full octet, eight electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
Elements react with other elements based on the number of electrons in their outer shell, also called valence electrons.
both have a nucleus of protons and neutrons and outer orbits of electrons
A group of elements that rarely combine with other elements because they already have eight electrons in the outer shells is a Noble Gas
Eight, except for helium which has two.

The outer electrons in krypton are eight electrons.

Yes mercury has two outer electrons the two elements that the two outer electrons would be Iodine and Magnesium.
All elements in the oxygen family have 6 electrons in the outer orbit.
The number of elements that contain the same type of outer electrons as sodium is 11.
