Why noble gases do not form ions?
They already have the perfect number of electrons in their topmost energy levels. hence they do not form ions. Noble Gases have no reaction to any of the elements under room temperature. However noble gases like krypton or xenon are known to form covalent compounds like KrF2, XeF4, XeOF4 etc.
Why are noble gases located on the periodic table?
The outer most shell contains eight electrons which is known as octate.(exceptional case : Helium which contains two electrons in its valence shell. Thus, it is known as Duplet)Nobel gases show similar chemical properties as the no. of electrons in the outermost shell is same. Hence they have similar chemical propertiesTheir valency is 0
Pick out the correct match or matches of element and number of valence-shell electrons a oxygen6 b chlorine8 c phosphorus5 d nitogen3 e carbon4?
a) Oxygen has 6 valence-shell electrons. c) Phosphorus has 5 valence-shell electrons. d) Nitrogen has 3 valence-shell electrons. e) Carbon has 4 valence-shell electrons.
How many valence electrons do h2o have?
8. Hydrogen has 1 valence electron, Oxygen has 6. Since H2O has two hydrogen atoms, Water has 6 + 1(2) = 8 valence electrons.

How many number of valence electrons in bromine?
Counting the 4th shell orbitals and their electrons, Bromine has two 4s electrons and five 4p electrons, giving it a total of 7 valence electrons.
How many valence electrons do all elements in group 2 of the periodic table?
they have 2 valence electrons, group 1 have 1 valance e-, group 2 have 2 e-, group 3-12 is depends on the chemical, group 13 have 3 e-, group 14 have 4 e-, group 15 have 5 e-, group 16 have 6 e-, group 17 have 7 e- and noble gases have 8 e-
How many e- is valence electrons?
Valence electrons are placed in the outermost shell of electrons.

How many valence electrons does Na have?
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.
